In 1833, Maryland established a course in preventive medicine, the first in America. The course was conceived and taught by Robley Dunglison, MD, professor of materia medica and therapeutics, hygiene and medical jurisprudence who served as dean from 1834 to 1836.      

In 1908, the medical school’s library relocated to an old church building on the southeast corner of Lombard and Greene streets. The building was given the name Davidge Hall, in honor of one of the school’s founders and first dean, John Beale Davidge, MD. The title would be transferred to the old medical building after the library’s demolition
in 1958.

In 1958, F. Mason Sones Jr., ’43D, discovered that arteries of the heart could be invaded safely with catheter and dyes in order to photograph their configuration. His technique, cine coronary angiography, became the gold standard for pinpointing coronary artery disease. From 1950 until his death in 1985, Sones was affiliated with the Cleveland Clinic Foundation.
