Heinrich Schnitger
Heinrich Schnitger (10 May 1925 in Lemgo - 27 August 1964 in Upper Bavaria) was a German physician. He is considered the inventor of the piston stroke Micropipette, a laboratory device for dispensing small amounts of liquid.
==Life==
Heinrich Schnitger was born in 1925 in Lemgo, Westphalia, Germany, the son of an inventor who designed, among other things, a once widely used bicycle lock. As a young boy, Schnitger had already tinkered with and made many changes and improvements to various gadgets. After suffering from tuberculosis as a soldier in the Second World War, he decided to study medicine. He attained PhD after studying medicine in 1956 at the Philipps University of Marburg with a thesis on the development of a device for the automated determination of blood clotting times . During his subsequent work at the Institute of Physiological Chemistry University of Marburg, among other things, he worked on large amounts of chromatography samples with a volume of less than a milliliter for further analysis. At that time the usual method was to use thin glass pipettes in which the fluids were aspirated directly or via a hose to the mouth.
Heinrich Schnitger constructed in the spring of 1957 in cooperation with the mechanical workshop of the Institute for this work a novel device with which it was possible to dispense small amounts of fluid quickly and precisely by hand. In the same year he presented under the title "A rapid and precise pipetting of small liquid quantities" a patent at the German Patent Office one, issued in 1961. The company Eppendorf improved the first "Marburg pipette" sold apparatus in cooperation with Heinrich Schnitger on and took over the exclusive license of the patent for commercialization.
Heinrich Schnitger died in 1964, before the global spread of his invention, due to an accident while swimming in a mountain lake in Upper Bavaria.
