Sir William Bowman

Born 20 Jul 1816; died 29 Mar 1892 at age 75.(1st Baronet) was an English surgeon and histologist who obtained a European reputation for medical research long before he was thirty years of age. He described (1842) the histologic structure of the nephron, the functional unit of the kidney, where the process of of urine takes place as a by-product of blood filtration that is carried on in the kidney. The "Bowman's capsule" of the kidney carries his name. The kidney contains millions of very tiny sacs called Bowman's capsules that filter blood to produce urine. He also made important discoveries concerning the structure and function of the eye and of striated muscle. He collaborated with Todd in writing The Physiological Anatomy.
