Thomas Leidy Rhoads, MD 1893, served in the Spanish-American War and World War I. He was the commanding chief surgeon of the American Expeditionary Forces in France, and received the Distinguished Service Medal at the close of the war. He later became the surgeon in charge of Walter Reed General Army Hospital.
President William Howard Taft selected Rhoads as his personal physician while he was in the White House. Rhoads also became Taft’s aide de camp when the man holding that position died in the Titanic disaster.
In addition to Keen, three other Jeffersonians tended to President Woodrow Wilson and the Wilson family — Francis X. Dercum, MD, John C. Da Costa, MD 1885, and Edward P. Davis, MD 1888.
Francis Xavier Dercum, MD, was a neurologist who specialized in the treatment of nervous and mental disorders. He joined Jefferson in 1892 when the medical college established a chair in nervous and mental diseases; he was the first to hold the position, and he remained as emeritus after retiring.
When President Wilson collapsed in the White House in October 1919, Dercum was called to treat him. He diagnosed Wilson with thrombosis but advised him to remain in office as an incentive to recover.
John C. Da Costa, MD 1885 (no relation to Jacob Mendes Da Costa), was the successor to Keen as the chair of the Department of Surgery in 1907 and in 1910, became the first Samuel D. Gross Professor.
During World War I, Da Costa served as a junior lieutenant in the Navy and eventually rose to the rank of commander. In 1919, he sailed on The George Washington on a special mission to tend to an ailing Wilson during negotiations for the peace treaty of World War I and the League of Nations.
While Edward P. Davis, MD 1888, did not attend to Wilson, in 1919 he delivered one of the president’s grandchildren, Woodrow Wilson Sayre. Davis, who had been a classmate of Wilson at Princeton, served as professor of Obstetrics from 1898 to 1925.
