Taylor proposed in their publication in Science that in normal blood and in citrated normal plasma rendered free from platelets by Berkefeld filtration, a substance was identified which, in small quantities, reduced the clotting time of hemophilic blood. Van Creveld demonstrated that a “dispersed protein” fraction obtained from the serum decreased the clotting time of hemophilic blood. This finding hinted towards a deficiency in the plasma. Gatia proposed that the platelets from hemophilic blood behaved normally when shifted to normal plasma. Addis investigated several blood and tissue factors and concluded that the hemophilic blood has defective prothrombin. Lossen proposed a deficiency in thrombokinase associated with hemophilia and disproved the association with calcium deficiency. Wright was the first who documented the prolonged clotting time of hemophilic blood in a capillary tube in 1893. William Bulloch and Paul Gordon Fildes published a detailed description of the early history of hemophilia in 1912 under the title 'Treasury of human inheritance'.Koller and his group in 1954, and Victor A. Hay was followed by the analyses from Sir William Osler in 1885, Kathleen P. The analysis of a hemophilia family tree by John F.Grandidier in 1855, John Wickham Legg in 1872, and Hermann Immermann in 1879. Nasse's law prompted further scientific debate leading to publications by J.A German physician, Johann Lukas Schönlein and his student Friedrich Hopff, documented the word 'hemophilia' for the first time in 1828 and the condition was described in his dissertation with the title 'About hemophilia or the hereditary predisposition to fatal bleeding'.Christian Friedrich Nasse, a German physician and psychiatrist, described the genetics of hemophilia in 1820 and his work resulted in Nasse's law, which states that hemophilia is transmitted entirely by unaffected females to their sons.Hay published his first analysis of a hemophilia family tree in the New England Journal of Medicine. His work was published under the title “An account of an hemorrhagic disposition existing in certain families”.

He described a bleeding disorder, transmitted via unaffected females and affecting only males.

Dr John Conrad Otto, an American physician, takes the credit for the first modern description of hemophilia in 1803.

Consbruch of Bielefeld, Germany, described a bleeding disease very similar to hemophilia in 1793.

Abu Qasim Khalaf Ibn Abbas Al Zahrawi, a pioneer of modern surgery, known in the West as Albucasis or Zahravius, described suspected hemophilia cases in the 10th century.

Ancient religious script compilations, such as The Babylonian Tarmud, have also mentioned the condition along with relative fatal bleeding episode prevention.

References to a condition associated with bleeding and suggestive of hemophilia date back to the 2nd century AD.

Extensive work has been done over the centuries regarding the classification, inheritance pattern, and treatment of hemophilia. The first modern descriptions of the condition appeared during the 19th century.

Hemophilia is considered a very old disease with its history dating back to the 2nd century AD.
