Thomas Addis Jr. (27 July 1881 – 4 June 1949) was a Scottish physician-scientist from Edinburgh who made important contributions to the understanding of how blood clots work. He was a pioneer in the field of nephrology, the branch of internal medicine that deals with diseases of the kidney. Addis described the pathogenesis of haemophilia in 1911 and was the first to demonstrate that normal plasma could correct the defect in haemophilia.
