William Osler, MD, was the first physician-in-chief at the Johns Hopkins Hospital. A dedicated physician, on his deathbed in 1919 of pneumonia, he requested that his brain be sent to the Wistar Institute in Philadelphia for further study to see what traits might distinguish his brain from others.
Wistar did an anatomical study of his brain and other prominent individuals in the 1920s. No significant findings were reported. Wistar still houses Osler’s brain.
