The first clinical findings on sickle cell anemia was recorded by James Herrick in 1910.
December 1904, a patient named Walter Clement Noel was admitted to the Chicago Presbyterian Hospital. Apparently, he was suffering from anemia. Ernest Irons was looking at Noel’s blood when he noticed the irregularity in the shape of the blood cells. He called them “peculiar, elongated and sickle-shaped” blood cells.
Hedrick later did more research and discovered fully the disease and how it was possible in 1910.
