Samuel Gross (1897) is a bronze statue by sculptor Alexander Stirling Calder, created as a monument to the American surgeon Dr. Samuel D. Gross (1805–1884). It was commissioned for and originally installed at the Army Medical School in Washington, D.C., on what is now the National Mall. In April 1970, it was relocated to the campus of Jefferson Medical College (now Thomas Jefferson University) in Philadelphia, Pennsylvania. It currently stands on the Sidney and Ethal Lubert Plaza, within the square bordered by 10th, Walnut, 11th and Locust Streets.
