23 Oct. 1852–27 Feb. 1937
Winslow became a member of the teaching staff of the University of Maryland Medical School as assistant demonstrator of anatomy and rose through various positions to become chairman of surgery in 1902. He was one of the founders of the Woman's Medical College, Baltimore, where he also was professor of surgery (1882–93) and dean (1890–92). Additionally, in 1884 he held the chair of operative surgery and topographic anatomy at the Baltimore Polyclinic. He was on the surgical staff of a number of hospitals as well as a school for boys and an orphanage in Baltimore. A pioneer in performing several new operations in Maryland, he was among the first, if not actually the first, to introduce antiseptic surgery in Maryland.
Winslow was an active member of national, regional, and state medical societies, in which he held offices and contributed numerous important papers to their journals. He was a member of the North Carolina Society in Baltimore of which he once was an officer. In 1913 he was a founder of the American College of Surgeons and became a Fellow.
His role at the University of Maryland was an important one—it was largely through his efforts that the university hospital was built, and under his leadership the medical course was increased from two to three years and then to four. He was a regent of the university from 1891 to 1920 and on the board of trustees of the endowment funds of the university. He also served for twenty years on the executive council of the Association of American Medical Colleges.
In 1877 Winslow married Rebecca Fayssoux Leiper of Chester, Pa. Her great-grandfather, Dr. Peter Fayssoux of Charleston, S.C., had been surgeon general of South Carolina during the American Revolution. The Winslows had thirteen children: Nathan, John Leiper, FitzRandolph, Edwards Fayssoux, Mary Fayssoux, Jane Parry, Caleb, Eliza Leiper, George Leiper, Oliver Parry, Richard Randolph Parry, St. Clair Spruill, and Callender Fayssoux. A birth-right Quaker, Dr. Winslow died in Baltimore and was buried in the Friends' Harford Road Burying Ground.
