IAMM President 1920-1921

After receiving his MD from the Jefferson Medical College in 1886, William worked in a variety of positions, first as

Assistant Demonstrator of Pathologic Anatomy at Jefferson Medical College, and from 1896 to 1922 as Professor

of Pathology and Bacteriology at the same institution. He was the first full-time pathologist at Jefferson. Dr Coplin invented the grooved glass jar (the Coplin jar) which allowed slides to stand separated in a staining solution. He realised the need to have hospital-based laboratories and was instrumental in establishing them in Philadelphia.
