‘Some Welch rabbits’, a caricature of William H. Welch, an American physician and one of the “Big Four” founding professors at the Johns Hopkins Hospital, and his pupils. Illustration by Max Broedel.

Within the sphere of Welch’s influence “…grew up a band of devoted followers who received their inspiration from him and were prepared, when their time came, to carry elsewhere the spirit of his laboratory and the influence of his magnetic personality. These men were in truth his earliest disciples, and amongst them were some who were destined to leave their mark upon American medicine.” Published: 1910.
