Thomas Hodgkin RMS was a British physician, considered one of the most prominent pathologists of his time and a pioneer in preventive medicine. He is now best known for the first account of Hodgkin's disease, a form of lymphoma and blood disease, in 1832. Hodgkin's work marked the beginning of times when a pathologist was actively involved in the clinical process. He was a contemporary of Thomas Addison and Richard Bright at Guy's Hospital in London.

Guy's Hospital is an NHS hospital founded by Thomas Guy, located in the borough of Southwark in central London. It is part of Guy's and St Thomas' NHS Foundation Trust and one of the institutions that comprise the King's Health Partners, an academic health science centre.
