A Moment in History

William S. Halsted, MD

William S. Halsted, MD
(1852 – 1922)

American anatomist, teacher, and surgeon, William Stewart Halsted was born in New York City, USA to a wealthy family of English origin. His father was involved in charitable work and Governor and trustee to a city hospital. Not a brilliant student initially, Halsted took an undergraduate in Liberal Arts in Yale, CT., after which he entered the Medical College of Physicians at the Columbia College, where he excelled.

As a second-year medical student Halsted applied and obtained a position in surgery at a local hospital. In here he learned about Lister’s antiseptic technique and became an adamant proponent of it to reduce infection. In 1877 Halsted obtained his MD. After a short time as House Physician at the New York Hospital, Halsted traveled to Europe to further his education studying for two years at the Universities of Vienna, Leipzig, and W?rzburg.

Besides being at the forefront of surgical and antiseptic techniques (introducing the use of rubber gloves in surgery), Halsted was extremely concerned with the way medical students were taught in the US. He pioneered bedside clinical round discussions with the medical students after two years of basic sciences studies. Halsted developed the idea of a patient chart; he also developed the residency program for medical students in use today.

Halsted is probably the most influential researcher and surgeon at the turn of the century. He dedicated time to the study of intestinal anastomoses and the use of silk as a suture material. His experimental work in 1887 proved that the inclusion of the submucosa layer in an anastomosis was mandatory, as well that a single layered anastomosis was enough to attain closure. Perhaps Halsted’s most important contribution was the application and use of the scientific method to surgical questions. Halsted’s principles set the standards used today in surgical suturing and surgical stapling.

He also pioneered the development and surgical techniques for radical mastectomy as a treatment for breast cancer.

As a side effect of this studied in anesthesia and the use of cocaine for anesthesia, Halsted became addicted to this substance, a problem that followed him through the years. Without impairing his capacity as a researcher and a surgeon, Halsted eventually recovered. He died in Baltimore in 1922 as a complication to surgery.

UPDATED: The root term [-mast-] arises from the Greek [μαστός] or [mastos] meaning "breast". A synonymous prefix is [mamm-] from the Latin [mamma], also meaning "breast".  This prefix is used in medical terms such as:

  • Mastectomy: The suffix [ectomy] means "removal of". Removal of the breast. This is an old operation, the first known records are from 180 A.D. The modern operation for radical mastectomy with careful removal of the related lymphatics was developed by William Halsted (1852 - 1922). The synonym [mammectomy] is correct, though rarely used. The word [masectomy] to refer to this procedure is incorrect and should not be used
  • Mastoptosis: The suffix [-(o)ptosis] means "to fall", "to sag" or "go down". A falling or sagging of the breast. (Syn. mammoptosis)
  • Mastoid: The suffix [oid] means "similar to". Similar to a breast or with the shape of a breast, such as the mastoid process, a bony prominence of the temporal bone. See accompanying image
  • Mastoplasty: The suffix [-(o)plasty] is used to mean "surgical reshaping". Surgical reshaping of the breast. Better known as a mammoplasty
  • Mastopexy: A type of mastoplasty. The suffix "opexy" is used to mean "surgical fixation". Surgical fixation of the breast. In a mastopexy, the breast is "fixed" higher to reduce the mastoptosis. (Syn. mammopexy)

There is an interesting evolution of this word. The above applies only when the term [-mast-] is used as a root term, and combined with other word components. From the Greek, this term was passed on to Latin and thence evolved with the German term [m?sten] meaning "to feed" or "to fatten". This is why we have [mast cells] in histology. These are a type of mononuclear leukocyte described by Paul Ehrlich (1814 - 1915) in 1879, who named them [maztellen], which in German means "a well-fed cell".
