Prof John Berry Haycraft FRSE (1859–1922) was a British professor in physiology who carried out important medical research.

Biography[edit]

Haycraft was born in Lewes, East Sussex, England, in 1859 and received his medical education at Edinburgh University. He worked for a time in Ludwig's laboratory in Leipzig.

In 1880 he was elected a Fellow of the Royal Society of Edinburgh. His proposers were Peter Guthrie Tait, William Rutherford Sir William Turner, and Sir Thomas Richard Fraser.[1]

In 1881 he was appointed chair of physiology at Mason College (which later became the University of Birmingham). He taught in Birmingham and attracted many students to the city. During his years in Birmingham and Edinburgh, Haycraft had been actively engaged in research and published papers on the coagulation of blood and in 1884, he discovered that the leech secreted a powerful anticoagulant, which he named hirudin, although it was not isolated until the 1950s, nor its structure fully determined until 1976.

Haycraft returned to London in 1892 and was appointed a research scholar of the British Medical Association.

In 1893 he was appointed chair of physiology at University College, Cardiff, where he worked until retirement in 1920. Haycraft died three years later.

He died on 30 December 1922.[2]
