In a series of investigations starting in 1906, Robert R. Bensley demonstrated that the islets of Langerhans were specialized elements of the pancreas. He developed staining methods that distinguished between alpha cells and the beta cells that produce insulin. Bensley's work was fundamental to the discovery of insulin. He later developed techniques to disassemble cells and isolate cellular components by spinning them in a centrifuge, a technique he used in 1934 to isolate mitochondria.
