School of Medicine
Department of Medicine

Established in 1978 by the estate of J. Earl Moore in memory of William Osler

OslerWilliamSIR WILLIAM OSLER, one of Hopkins’ four founding doctors, served as physician-in-chief and professor of medicine. He was a proponent of the close integration of the hospital with the instruction of students in the School of Medicine–a model emphasizing teaching at the bedside that he pioneered at Johns Hopkins. Through lectures and his landmark textbook, first issued in 1892, Principles and Practice of Medicine, he had a tremendous influence on both clinical practice and medical education in America. During the 14 years he spent at Hopkins, Dr. Osler revolutionized the medical curriculum of the United States and Canada, ushering in the era of scientific medicine and creating policies and programs that have endured. Dr. Osler was a skilled diagnostician, a generalist who believed physicians should be knowledgeable in a broad range of specialties. He did seminal work in hematology. He also published amusing and inspiring essays and speeches, still popular among physicians. Perhaps his most lasting legacy was his vision of how a physician ought to be: skillful and competent, yet approachable and compassionate.
