A Moment in History

Andreas Vesalius Bruxellensis (1514- 1564)

A Flemish anatomist and surgeon, Andreas Vesalius was born on December 31, 1514 in Brussels, Belgium. He is considered to be the father of the science of Anatomy. Up until his studies and publications human anatomy studies consisted only on the confirmation of the old doctrines of Galen of Pergamon (129AD - 200AD). Anatomy professors would read to the students from Galen's work and a demonstrator would point in a body to the area being described, if a body was used at all. The reasoning was that there was no need to dissect since all that was needed to know was already written in Galen's books. Vesalius, Fallopius, and others started the change by describing what they actually saw in a dissection as opposed to what was supposed to be there. 

Vesalius had a notorious career, both as an anatomist and as a surgeon. His revolutionary book "De Humani Corporis Fabrica: Libri Septem" was published in May 26, 1543. One of the most famous anatomical images is his plate 22 of the book, called sometimes "The Hamlet". You can see this image if you hover over Vesalius' only known portrait which accompanies this article. Sir William Osler said of this book "... it is the greatest book ever printed, from which modern medicine dates" 

After the original 1543 printing, the Fabrica was reprinted in 1555. It was re-reprinted and translated in many languages, although many of these printings were low-quality copies with no respect for copyright or authorship.

The story of the wood blocks with the carved images used for the original printing extends into the 20th century. In 1934 these original wood blocks were used to print 617 copies of the book "Iconaes Anatomica". This book is rare and no more can be printed because, sadly, during a 1943 WWII bombing raid over Munich all the wood blocks were burnt.

One interesting aspect of the book was the landscape panorama in some of his most famous woodcuts which was only "discovered" until 1903.

Vesalius was controversial in life and he still is in death. We know that he died on his way back from a pilgrimage to Jerusalem, but how he died, and exactly where he died is lost in controversy. We do know he was alive when he set foot on the port of Zakynthos in the island of the same name in Greece. He is said to have suddenly collapsed and die at the gates of the city, presumably as a consequence of scurvy. Records show that he was interred in the cemetery of the Church of Santa Maria delle Grazie, but the city and the church were destroyed by an earthquake and Vesalius' grave lost to history. Modern researchers are looking into finding the lost grave and have identified the location of the cemetery. This story has not ended yet.

Personal note: To commemorate Andrea Vesalius' 500th birthday in 2014, there were many scientific meetings throughout the world, one of them was the "Vesalius Continuum" anatomical meeting on the island of Zakynthos, Greece on September 4-8, 2014. This is the island where Vesalius died in 1564. I had the opportunity to attend and there are several articles in this website on the presence of Andreas Vesalius on Zakynthos island. During 2015 I also attended a symposium on "Vesalius and the Invention of the Modern Body" at the St. Louis University. At this symposium I had the honor of meeting of Drs. Garrison and Hast, authors of the "New Fabrica". Dr. Miranda

Leon Hirsch and the founding of the United States Surgical Corporation

This article is part of the series "A Moment in History" where we honor those who have contributed to the growth of medical knowledge in the areas of anatomy, medicine, surgery, and medical research.

Leon C. Hirsch
Leon C. Hirsch


Leon C. Hirsch
(1927 – 2023). The story of the development of surgical staplers in America cannot be told without the presence and vision of Leon Hirsch, an American business executive and entrepreneur... 

After his 1958 trip to the USSR with two other surgeons, Dr. Mark Ravitch tried to have his colleagues take interest in the surgical stapling technology. Dr. Ravitch and Dr. Felicien Steichen stated in one of their books “Interestingly enough, a number of American manufacturers, knowing of our interest, visited our laboratories and operating rooms to see how the staplers performed, but for one reason or another decided that there was no future in stapling – to their later expressed regret! (1)”

There have been several apocryphal stories, including one where L. Hirsch was a down-on-his luck shoe salesman (not true) that met with his friend Ravitch as they both lived close to each other (not true either). So, what is the real story of how Leon Hirsch met Mark Ravitch and founded the United States Surgical Corporation (USSC).?

The original story, as told by Leon Hirsch, can be found in the May 1990 edition of the medical journal “Surgical Rounds” (2), an edition entirely dedicated as a “Festschrift (commemorative publication) to Mark Ravitch, MD”, after his death.

Leon Hirsch says: “In 1963, I was engaged in a discussion with a patent broker in New York City when I noticed a strange-looking metal object on his desk, which he described to be a Russian surgical stapler. Further inquiry led to the disclosure that this patent broker had been retained by the Russian government to try to market Soviet-made surgical staplers in America”. This patent broker had tried to garner the attention of at least five companies (Ethicon, Davis & Geck, American Hospital Supply, Aloe Corp., and Ipco, Inc) with no success.

This statement by Leon Hirsch goes against everything I knew, that is, that Dr. Ravitch was the one trying to bring the patents from the then USSR to the USA. In another version of this story Dr. Ravitch bought the patents and tried to sell them to USA medical companies! None of these are true.

Leon Hirsch continues “The patent broker offered to lend me his information book on Russian stapling… the package disclosed that recently, three American surgeons had been to Moscow to study Russian surgical techniques, including the technique of surgical stapling”. This statement by the Soviet government is not correct, as Dr. Ravitch and two other surgeons had been to Moscow, yes, but to study Russian transfusion and resuscitation techniques, and the fact that they ended observing surgery (and seeing surgical staplers at work) was serendipitous. That in itself is another story.

Leon Hirsch phoned Dr. Ravitch who at the time was working at John Hopkins. They planned to meet for 15 minutes, which stretched into lunch, then back to Dr. Ravitch’s office for a demo of the staplers. The discussion veered into the difficulty of loading the staples one by one in this large, cumbersome device. “Intrigued, I asked Dr. Ravitch to borrow the instrument, took it back to my home workshop, and realized that the answer to the loading problem was to separate the instrument from the staples. I made a model of a cartridge (in balsa wood) that could be preloaded with staples and easily slipped into the instrument. Dr. Ravitch was elated”. The idea of the interchangeable cartridge was Hirsch's!

With this idea, and financial support that he pursued, Leon Hirsch proceeded to form the United States Surgical Corporation, with four initial employees. It took three years (1964-1967) to develop a stainless steel surgical stapler that had interchangeable preloaded stapler cartridges that were up to American standards. Since then, thousands of patients have benefited from these devices.

An interesting side note is that Leon Hirsch wanted Mark Ravitch to play a part in this new company, but Ravitch declined. Hirsch states: "Dr. Ravitch said that he had no commercial interest in pursuing such a project but he would be willing and happy tp evaluate, first in the laboratory and if successful clinically, such new devices. In typical Ravitch fashion he added that he planned to report exactly what he found, good or bad". 

The story of USSC continued through acquisitions, so USSC became Tyco, then Tyco Healthcare, Covidien, and today is the Stapling Division of Medtronic.

Leon Hirsch and USSC confronted the conundrum of training surgeons in the use of the new staplers. To this end he initially hired eight nurses, but eventually created a six-week extremely difficult grueling training program that took sales representative from basic medical terminology to being able to direct the surgeon through the steps on the use of the surgical staplers in the procedure. By doing this, he changed the way medical devices surgical representatives operate in the medical arena. Some of the readers of this article probably went through this challenging training program! In fact, some medical companies started trying to hire people that had been trough this training.

Drs. Ravitch and Steichen continued their quest training surgeons on the benefits of surgical stapling, while at the same time testing and improving the newer devices that Leon Hirsch and USSC developed.

In 2018, The Mullings Group interviewed Leon Hirsch (then 91 years old) and published a video of this interview, where he covers these topics and more. This video now forms part of the History of Surgical Stapling.

An incredible find in surgical stapling history

This article is part of the series "A Moment in History" where we honor those who have contributed to the growth of medical knowledge in the areas of anatomy, medicine, surgery, and medical research.

Dr. Mark M. Ravitch
Dr. Mark M. Ravitch


Young surgeons today use surgical staplers without a thought as to the history of the development of these surgical devices. The same is true for many who work in the medical devices (surgical staplers) industry. I have worked as a consultant and a trainer for the stapler industry both with Ethicon Endosurgery (today Ethicon, stapling division) and the United States Surgical Corporation (today Medtronic, stapling division) and developed a special interest in the medical history related to the origin, research, and development of surgical staplers.

The history of surgical stapling is quite interesting and has many characters, starting with the early works of Humer Hutl. There are whole books dedicated to this topic.

It cannot be denied that one of the main drivers of surgical stapling in the United States was Dr. Mark M. Ravitch (1910-1989). History tells us that he saw these staplers in action being used by Dr. Nikolai Mikhailovich Amosov (1913–2002) during a visit to the Thoracic Surgical Institute in Kiev in September 1958. Kiev was then part of Russia (then called the USSR).

What I did not know is that Dr. Ravitch had his notes typewritten, and those loose leaf notes are now part of my library in a binder.

The notes in this binder are the carbon copies in onionskin paper of notes typewritten personally by Dr. Mark. M. Ravitch during his trip to the USSR in September 1958. According to his family, Dr, Ravitch had notoriously bad handwriting and he liked to maintain records of his work, so he was a very fast typewriter. He used his personal typewriter and he traveled everywhere with it even during his military service in WWII.

The original notes were bound in a book (also in my collection) and gifted by Dr. Ravitch to his parents. Unfortunately, the paper he used for the originals was not acid-free and the pages in this unique book are slowly crumbling and some of them are today unreadable. Thankfully, the carbon copies are acid-free, and the pages have been carefully scanned in TIF and PDF format by David M. Klein and then placed in separate plastic sleeves for preservation in a binder that is now in my library.

After Dr. Ravitch’s parents passing, both these notes were in the library of his son, Michael M. Ravitch, Ph.D. Michael lent these notes to Dr. Felicien Steichen (1926 – 2011) , who after a time returned the notes with a letter, also included in this binder. In this letter Dr. Steichen says that these notes should be preserved for future research, even mentioning Leon Hirsch (CEO of the United States Surgical Corporation) to support this endeavor.

Michael Ravitch’s widow, Myrnice Ravitch contacted me in 2017 because of my interest in medical history and the life and work of Dr. Ravitch. She donated some books that were in Dr. Ravitch’s library. In early 2024, and with the blessing of Dr. Ravitch’s daughter Binnie and the rest of the Ravitch family, they donated these notes that are now part of the history of surgical stapling and are today part of my library.

In a separate article I will present some of the actual notes regarding surgical stapling, although these notes also include invaluable observations on medicine and surgery in the USSR and Dr. Ravitch’s comments on the Russian culture and people at the time. Keep in mind that Dr. Ravitch’s parents where Russian immigrants and he was fluent in Russian.

In the future, and following Dr. Steichen’s suggestion, I will try to publish a book with these notes along with additional notes on Dr. Ravitch’s trip to China in 1983

Note: The photograph of Dr. Asomov was taken by Dr. Ravitch, but it has since degraded, so it was enhanced using Winxvideo AI.

Note: Dr. N.M. Amosov had an incredible surgical career and recognized with medals and honors. The Institute where Dr. Ravitch saw him operate with surgical staplers is today known as the Amosov National Institute of Cardiovascular Surgery in Kiev, Ukraine.

Anton Nuck

This article is part of the series "A Moment in History" where we honor those who have contributed to the growth of medical knowledge in the areas of anatomy, medicine, surgery, and medical research.

Anton Nuck

Antonius Nuck


Anton Nuck (1650-1692), a Dutch surgeon and anatomist used several forms for his name such as Antonio Nuck, Anton Nuck, Antonii Nuck, and Antonius Nuck van Leyden. Born in Harderwijk, Netherlands, he moved to Leyden in South Holland, where he studied medicine at the University of Leyden. He received his doctorate in February 1677 with this thesis “De Diabete”.

In 1683 he became a reader (lecturer) of anatomy and surgery at the Collegium Anatomicum Chirurgicum, in Haag (The Hague, Netherlands). He returned to his alma mater in Leyden, where the was appointed to the chair of Medicine and Surgery.

Nuck is known today for the first description of  the processus vaginalis, a peritoneal evagination thar runs lateral to the gubernaculum into the inguinal canal in the fetus, both male and female, terminating in the labioscrotal fold, an area that will become the scrotum in the male or the labium majus in the female. This canal is known eponimycally today as the "Canal of Nuck"

The processus vaginalis in the male runs lateral to the vas deferens into the scrotum. The processus vaginalis in normally closed, but if it stays patent, it becomes a passageway for abdominal contents into the scrotum, setting the stage for an indirect inguinal hernia.

Plate XL of Adenographia (Nuck)

In the female the processus vaginalis runs lateral to the round ligament of the uterus. Since the round ligament ends in the labium majus, a patent processus vaginalis sets the stage for an indirect inguinal hernia that bulges into the labium majus (see figure 4 in Source 1- WARNING the image depicts external female genitalia)

Before Nuck, it was argued that females could not have inguinal hernias. In 1691 Nuck published his book "Adenographia Curiosa & Uteri Foeminei Anatome Nova", where he showed that indeed some females could indeed have hernias. For additional information on the canal of Nuck and the text in the book, click here

Chapter 10 of this book is entitled “De Peritoneai Diverticulis Novis” (On a New Peritoneal Diverticulum”.  Not only Nuck described the processus vaginalis, but he described a pathology today known as “Nuck’s cyst” or “Nuck’s hydrocele”, a cyst within Nucks’ canal.  The images above show the title page of his book "Adenographia Curiosa & uteri foeminei anatome nova" and a composite image of plate XL and text. This book was dedicated to the mainly to the topic of lymphatic vessels. The discovery of a patent processus vaginalis was not its intent, but when he found it, he added it to his book. The text on image XL reads "diverticulum novum oculis subjiciens, ex subjecto humano" that can be freely translated as "On a new opening, seen with our eyes in a human subject"

Because of laparoscopic and robotic surgery that requires a pneumoperitoneum, an undiagnosed patent canal of Nuck can lead to a pneumatocele or pneumolabium (See Sources 6)

Besides general surgery, Anton Nuck practiced dentistry and ophthalmic surgery, being the first one to perform a paracentesis for hydrophthalmia (glaucoma) to reduce the pressure inside the eye. He also performed the first recorded vitrectomy. He studied the salivary glands and called the process sialography.

Musculi levator labii superioris alaeque nasi

musculi levator labii superioris alaeque nasi
Click for a larger image


UPDATED:The [musculi levator labii superioris alaeque nasi] is one of the superficial muscles of expression found in the face. It is a small bilateral muscle found at the angle of the nose and its function is to elevate the superior lip and the side ("wing") of the nose, slightly opening or "flaring" it. When both of these muscles are activated the facial expression attained is called a "snarl".

Its name is Latin and can be loosely translated  as the "muscle that lifts the upper lip and the wing of the nose". The muscle attaches to the superior  frontal process of the maxilla and inserts into the skin of the lateral part of the nostril and upper lip.

This muscle has two components, one superficial and the other deep. From the insertion point (see red arrow in accompanying image), the deep muscular fibers insert in the skin of the posterior aspect of the nasal wing. The external muscle fibers cross superficially over the orbicularis oris muscle and insert in the deep skin of the upper lip towards the lip anle.

My friend Dr. Elizabeth Murray calls it "a small muscle with the longest name in human anatomy". Fact is, I think she is right! It is worse in Spanish, where the name of the muscle is "músculo elevador común del ala de la nariz y del labio superior"!

Book: "La Forma Humana de la línea"

Book Cover, cropped
Book cover, cropped


I recently added a new book to my library. It is in Spanish and titled "La Forma Humana de la Línea", which can be loosely translated to "The Human Form of the Line", referring to the hand-drawn images of human skeletal anatomy in the book.

"La forma humana de la línea" Katherine Estrada Suazo. ISBN 9789564021898, 2020. América Impresores. Valdivia, Chile

This is an extraordinary book that depicts in 90 pages and 40 plates the human bony anatomy in beautiful detail using a technique described by Leonardo Da Vinci in his “Trattato della Pittura” (A Treatise on Painting), chapter CXXVI. The author, Katherine Estrada Suazo, draws in hyperrealist detail single bones, a full skeleton, fetal skeletons in a seldom seen detail.

The introduction, the words of the artist, the analysis of Leonardo Da Vinci's technique, and the closing comments are a rare form of high level prose with mastery of the Spanish language that reads almost like poetry.

The book itself is a printing marvel. An uncommon large size (9½ by 15¾ inches/24 by 40 cm.), in a high quality acid-free heavy paper, with beautiful typesetting. The book also includes one large insert measuring 29½ by 9 inches (75 by 23 cm).

This work was supported by Morphology Professor, Patricia Hernández Coliñir at the Anatomy Unit of the Medical School of the Universidad Austral de Chile in the city of Valdivia, where it was printed by the América Impresores printing press. The author also received support from the Chilean government through the Regional FONDART (Regional Ministerial Secretary of Culture, Arts and Heritage). As far as I understand, this book is not for sale, which makes it a rare book.

I became aware of this book at the XLIII Annual Chilean Meeting of Anatomy, where I was invited to present the conference I delivered initially in May 2023 at the University of Antwerp, Belgium. An anatomy professor of the Universidad Austral de Chile, Ana Barriga K., had a copy of the book that was gifted to Dr. Carlos Machado, a good friend and famous medical illustrator of Netter’s Anatomy Atlas.

The road to obtaining the copy of the book included contacting the author and with the help of Professor Barriga, and a friend from Chile, the book went from Valdivia (Chile) to Santiago (Chile), to Mexico, and the US. This copy is dedicated by the author as follows: “Dedicated to Dr. Efrain Miranda. Signed in Valdivia, June 2024”, followed by her signature.

In a recent conversation with the author, she stated that "restricting access to this publication was never my intention", and although having the signed book for me is very important, Ms. Estrada has authorized the open download of the digital edition of the book in PDF format, which you can download here. (19 Mb)

Personal remark: As a side note, the city of Valdivia in Chile, where this book was designed and printed, is the city where my mother was born. Dr. Miranda



Lámina1: Cráneo, vista súperolateral


Recientemente agregué un nuevo libro a mi biblioteca. Está en español y se titula "La Forma Humana de la Línea", en referencia a las imágenes dibujadas a mano de la anatomía esquelética humana que aparecen en el libro.

"La forma humana de la línea" Katherine Estrada Suazo. ISBN 9789564021898, 2020. América Impresores. Valdivia, Chile

Este es un libro extraordinario que describe en 90 páginas y 40 láminas la anatomía ósea humana con hermoso detalle utilizando una técnica descrita por Leonardo Da Vinci en su “Trattato della Pittura” (Tratado sobre la pintura), capítulo CXXVI. La autora, Katherine Estrada Suazo, dibuja con detalles hiperrealistas huesos individuales, un esqueleto completo y esqueletos fetales con un detalle pocas veces visto.

La introducción, las palabras del artista, el análisis de la técnica de Leonardo Da Vincy y los comentarios finales son una forma poco común de prosa de alto nivel con dominio del lenguaje español que se lee casi como poesía.

El libro en sí es una maravilla de impresión. Un tamaño grande poco común (9½ por 15¾ pulgadas/24 por 40 cm.), en un papel pesado libre de ácido de alta calidad, con una hermosa composición tipográfica. El libro también incluye un inserto grande que mide 29½ por 9 pulgadas (75 por 23 cm).
Este trabajo fue apoyado por la Profesora de Morfología, Patricia Hernández Coliñir en la Unidad de Anatomía de la Facultad de Medicina de la Universidad Austral de Chile en la ciudad de Valdivia, donde también fue impreso por la imprenta América. El autor también recibió apoyo del gobierno de Chile a través del Fondart Regional (Secretaría Regional Ministerial de Cultura, las Artes y el Patrimonio). Según tengo entendido, este libro no está a la venta, lo que lo convierte en un libro raro.

Me enteré de este libro en la XLIII Reunión Anual Chilena de Anatomía, donde me invitaron a presentar la conferencia que di inicialmente en mayo de 2023 en la Universidad de Amberes, Bélgica. Una profesora de anatomía de la Universidad Austral de Chile, Ana Barriga K., tenía una copia del libro que fue obsequiada al Dr. Carlos Machado, un buen amigo y famoso ilustrador médico del Atlas de Anatomía de Netter.

El camino para obtener la copia del libro incluyó contactar al autor y con la ayuda de la profesora Barriga y un amigo de Chile, el libro viajó desde Valdivia (Chile) a Santiago (Chile), a México y a los Estados Unidos. Este ejemplar está dedicado por la autora de la siguiente manera: “Dedicado al Dr. Efraín Miranda. Firmado en Valdivia, junio de 2024”, seguido de su firma.

En una reciente conversación con la autora, ella afirmó que “nunca fue mi intención restringir el acceso a esta publicación”, y aunque tener el libro  firmado para mí es muy importante, la autora ha autorizado la descarga abierta de la edición digital del libro en formato PDF, que pueden descargar aquí. (19 Mb)

Observación personal: Como nota al margen, la ciudad de Valdivia en Chile donde se diseñó e imprimió este libro, es la ciudad donde nació mi madre. Dr. Miranda.


The Ether Dome

This article is part of the series "A Moment in History" where we honor those who have contributed to the growth of medical knowledge in the areas of anatomy, medicine, surgery, and medical research.

Ether Dome Skylight
Ether Dome Skylight

During one of many trips this year, I found myself with a free day in Boston, Massachusetts. Had a recommendation to try and visit the Ether Dome, which I did, and it was an interesting, although short, experience.

The Ether Dome is the name given by the Massachusetts General Hospital (MGH) to the first operating room of the MGH and it is located under the dome at the top of the Bullfinch Building, named after its architect Charles Bullfinch (who later became one of the architects for the USA Capitol). The reason for the location of the operating room is that there is a large skylight that provided the light for the operations.

The operating room was in service between 1821 and 1867 and over 8,000 operations were performed here. It was later used as a storage are, a nurse’s dormitory, a dining room, and today as a teaching auditorium. It still has the arrangement of a semicircular staired pavilion, as in the early days of the operating room. The Ether Dome was designated a National Historic Site in 1965.

National Historic Site 1965

The reason for the name Ether Dome is that in this location, on October 16, 1846, anesthesia was used successfully for the first time. The surgeon was John C. Warren, one of the MGH’s founders. The anesthesiologist was William T. G. Morton, a dentist. The patient was Gilbert Abbott. The operation was the excision of a neck tumor. Upon waking up, the patient said that he had felt no pain.

Ether Dome Auditorium


This event was so revolutionary that painting and images have bee created all over to remember the occasion. One of most creative was the work done for a mural called “Ether Day, 1846” The artists were Warren and Lucia Prosperi, who in 2000-2001 took photographs of surgeons and administrators at MGH in period clothing in different poses to recreate the event of the first use of anesthesia. An oil painting of the mural can be seen at the Ether Dome.  If you are interested in visiting the MGH, I recommend planning your visit with the Paul S. Russel Museum of Medical History and Innovation. The museum itself is worth visiting. If you want, the Russel Museum has a virtual tour of the Ether Dome and the Hospital, click here.

Painting of the operation by Warren and Lucia Prosperi

Since the Ether Dome is an active teaching auditorium, it is not always available for visitors, to it is good to call ahead, I did not, and was lucky to enter the auditorium prior to a welcome meeting for first year medical students. What an historical location to begin your medical career!

The Ether Dome houses a plaster cast of a Roman statue, the Apollo Belvedere, an Egyptian mummy, and an old human skeleton used for teaching.

 A large plaque on the wall reads: ” On October 16, 1846 in this room, then the operating theatre of the Hospital, was given the first public demonstration of Anæsthesia to the extent of producing insensibility to pain during a serious surgical operation. Sulphuric ether was administered by William Thomas Green Morton, a Boston dentist. The patient was Gilbert Abbott. The operation was the removal of a tumor under the jaw. The surgeon was John Collins Warren. 
The patient declared that he had felt no pain during the operation and was discharged well, December 7. Knowledge of this discovery spread from this room throughout the civilized world and a new era for surgery began.”

Here is a photograph of a later operation in 1847 where Morton and Warren can be seen.

I have written several articles about this topic, the event, and its protagonists. Here are some of the links:
