Stephen Christmas (1947-1993) was a 5 year old boy when he became the first patient described to have Christmas disease (or Haemophilia B) in 1952 by a group of British doctors.

Biography

Steven was born to a British family in Canada, and was investigated for his severe bleeding disorder in Oxford, where it was discovered that he was not deficient in Factor VIII, which is normally decreased in classic haemophilia, but a different protein, which received the name Christmas factor in his honour (and later Factor IX).

Stephen was dependant on blood and plasma transfusions, and was infected with HIV in the period during which blood was not routinely screened for this virus. He campaigned for transfusion safety ever since getting infected, but developed AIDS, of which he died in 1993.
