Gerrit Friedrich Otto Toennies (January 31, 1898 in Hamburg, Germany – September 16, 1978 in Kensington, Prince Edward Island, Canada) was a research biochemist. He was the oldest of five children of the famous sociologist Ferdinand Tönnies and a brother of Jan Friedrich Tönnies.

Life
Toennies grew up in Eutin, Germany. He was drafted into the German army in 1916 and shortly after was taken prisoner of war. As a French prisoner 1916 – 1920 he was assigned to a gas works in Le Havre, France, where he became interested in chemistry. 1920 – 1924 he studied at Universities in Freiburg (1920), Munich (1921 – 1922) and Kiel (1922 – 1924), where in 1925 he received his Ph.D. in organic chemistry. His adviser was Otto Diels who together with Kurt Alder, received the Nobel prize in Chemistry in 1950. Toennies emigrated to the U.S. in 1926 where he joined the Texas Oil Company in Bayonne, New Jersey until 1929. Then he became a staff member of the Philadelphia Lankenau Hospital Research Institute (LHRI), which later was called the Institute for Cancer Research. The LHRI was founded by Stanley P. Reimann and Frederick Hammett in 1927 as one of the first U.S. laboratories devoted to fundamental cancer research. The present day Fox Chase Cancer Center stems from the LHRI. Toennies was head of the Department of Microbiology 1947 –1963. At retirement he was awarded the honorary position “Senior Member Emeritus” by their board of trustees. Subsequently, he became research professor at Temple University School of Medicine (1963 – 1968) and finally a visiting professor at the University of Göttingen and the “Biologische Bundesanstalt für Land- und Forstwirtschaft” in Braunschweig. Toennies was married to Dita Margarete Jebens (1903 – 1959) and Dorothy West (1903 – 2004). He is survived by Jan Peter Toennies (1930 - ) and Ralf Gerrit Toennies (1939 - ). Before his death he requested that his gravestone should have the words "Still Learning" placed on it. His wish was fulfilled by his sons.
Research
In 1940 Toennies was the first to point out the probable biological importance of sulfonium compounds – a prediction later borne out by a variety of findings by other investigators. Later, he was the first to demonstrate that the red blood cells are a major site of bound forms of folic acids, a group of vitamins that play an important role in rapid growth of tissues such as occurs in cancer. He also made pioneering contributions to our understanding of the role of various chemicals on bacterial growth.
Over the years Toennies developed chemical procedures so precise and useful that many of them have become standards. One of them – a method of oxidizing proteins with performic acid, was adopted by the British chemist, Frederick Sanger, in his research to determine the molecular structure of insulin that won Sanger the Nobel prize in 1958.
