The first record of hemophilia is in the Talmud, Jewish holy text, which states that males did not have to be circumcised if two brothers had already died from the procedure. In the 12th century, the Arab physician Albucasis wrote of a family whose males died of bleeding after minor injuries. Then, in 1803, Dr. John Conrad Otto, a Philadelphia physician, wrote an account about "a hemorrhagic disposition existing in certain families." He recognized that the disorder was hereditary and that it affected males and rarely females.He was able to trace the disease back to a woman who settled near Plymouth in 1720. The first usage of the term "hemophilia" appears in a description of the condition written by Hopff at the University of Zurich in 1828. In 1937, Patek and Taylor, two doctors from Harvard, discovered anti-hemophilic globulin.Pavlosky, a doctor from Buenos Aires, found Hemophilia A and Hemophilia B to be separate diseases by doing a lab test. This test was done by transferring the blood of one hemophiliac to another hemophiliac. The fact that this corrected the clotting problem showed that there was more than one form of hemophilia.
See main article at Haemophilia in European royalty
Hemophilia figured prominently in the history of European royalty and thus is sometimes known as "the royal disease". Queen Victoria passed the mutation to her son Leopold and, through several of her daughters, to various royals across the continent, including the royal families of Spain, Germany, and Russia. Tsarevich Alexei Nikolaevich, son of Nicholas II, was a descendant of Queen Victoria and suffered from haemophilia.
About 18,000 people in the United States have hemophilia. Each year, about 400 babies are born with the disorder. Hemophilia usually occurs in males and less often in females.
