In 1841, Jefferson Medical College hired what would be dubbed "The Faculty of '41", an influential collection of professors including Charles Delucena Meigs and Mütter Museum founder Thomas Dent Mütter. This collection of professors would institute numerous changes to Jefferson—including providing patient beds over a shop at 10th and Sansom Streets in 1844—and the staff would remain unchanged for 15 years.[14] The graduating class of 1849 included a son of college founder Joel Barlow Sutherland, Charles Sutherland, who went on to serve as Surgeon General of the United States Army.[15]
