Horton's syndrome

Horton, Bayard Taylor (1895–1980), American physician. Horton is known for classic descriptions of two clinical entities. In 1932 Horton and two colleagues from the Mayo Clinic described giant cell arteritis as a new disease entity. This disease, however, was actually described for the first time two years earlier by an American physician, Max Schmidt, in a study of intracranial aneurysms. In 1939 Horton described the condition now known as a cluster headache or Horton's syndrome.
