A Moment in History

Giovanni Battista Morgagni

(1682 - 1771)

Italian anatomist, physician, and pathologist, Morgagni was born in the city of Forli. He started his medical studies at the University of Bologna, graduating in 1701 with a degree in Medicine and Philosophy. In 1712 he became a professor of anatomy at the University of Padua, Italy, 175 years after Andreas Vesalius. Morgagni was offered and accepted the Chair of Anatomy in 1715 at the University of Padua. Although Morgagni held a position at the anatomy department of the University of Padua, his name is associated mostly with his pathological studies.

Morgagni was interested in the works of Theophile Boneti (1620 - 1689), who started analyzing the correlation between post-mortem anatomical findings and diseases. He tried to establish a relation between the disease and the cause of death. In 1761 Morgagni published his most influential work "De Sedibus et Causis Morburum Per Anatomen Indagatis"  (On the Sites and Causes of Diseases, Investigated by Dissection). His work was essential for pathological anatomy to be recognized as a science in itself.

Morgagni was elected to become a member of several Academies of Science and Surgery: The Royal Society of London, The Academy of Science in Paris, The Berlin Academy of Science, and the Imperial Academy of Saint Petersburg in Russia. He is remembered today by several eponyms in anatomy and pathology:

• Morgagni's caruncle or lobe, referring to the miidle lobe of the prostate
• Morgagni's columns: the anal (or anorectal) colums
• Morgagni's concha, referring to the superior nasal concha
• Morgagni's foramina: two hiatuses in the respiratory diaphragm allowing for passage of the superior epigastric vessels
 Morgagni's hernia: an hiatal hernia through Morgagni's foramen, in the respiratory diaphragm
• Morgagni's ventricle: an internal pouch or dilation between the true and false vocal cords in the larynx
• Morgagni's nodules: the nodules at the point of coaptation of the leaflets (cusps) of the pulmonary valve. Erroneously called the "nodules of Arantius", which are only found in the aortic valve

Henry Gray F.R.S


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.To search all the articles in this series, click here.

Henry Gray F.R.S. (1827 – 1861). English anatomist, Henry Gray was born in 1827. Not much is known of his early studies. What is known is that on May 6, 1845 Gray was studying as a pupil at St. George’s Hospital in London. At 21 years of age Gray won an award for an anatomical paper on human and comparative anatomy of the eye and its appendages.

In 1850 Henry Gray was appointed as house surgeon to the St. George’s Hospital, and in 1852 he was elected as a Fellow of the Royal Society. He wrote several anatomical papers and in 1852 became a lecturer on Anatomy at the same hospital.

At this time he started work on what would become his legacy to the world. A systematic analysis and treatise on human anatomy that was originally published in 1858, entitled “Anatomy, Descriptive, and Surgical” which was profusely illustrated by Henry Vandyke Carter, M.D.

Unfortunately for the world, Henry Gray was affected by smallpox and died on June 13, 1861 shortly after he was elected as a member of the Royal College of Surgeons. Henry Gray died when he was only 34 years old.

Much of the original work of Henry Gray is today in the public domain. Still, the book that he published is still in print, much modified, but with the same educational purpose. The 40th British Edition of “Gray’s Anatomy: The Anatomical Basis of Clinical Practice” was published in November 2008. The American Edition of the same book was published in 1908, long after his death. The 30thAmerican Edition of Gray’s Anatomy was last published in the USA in 1984.
