Theodor Förster
Theodor Förster (15 May 1910 – 20 May 1974) was a German physical chemist known for theoretical work on light-matter interaction in molecular systems such as fluorescence and resonant energy transfer. Education and careerFörster was born in Frankfurt am Main and studied physics and mathematics at the University of Frankfurt from 1929 to 1933.[1] He received his Ph.D. at the age of only 23 under Erwin Madelung in 1933. In the same year he joined the Nazi Party and the SA.[2] He then joined Karl-Friedrich Bonhoeffer as a research assistant at the Leipzig University, where he worked closely with Peter Debye, Werner Heisenberg, and Hans Kautzky. Förster obtained his habilitation in 1940 and became a lecturer at the Leipzig University.[3] Following his research and teaching activities in Leipzig, he became a professor at the Poznań University in occupied Poland (1942).[3][4] From 1947 to 1951 he worked at the Max Planck Institute for Physical Chemistry in Göttingen as a department head. In 1951, he became a professor at the University of Stuttgart.[3] He died due to a heart attack in 1974.[4] ResearchAmong Förster's greatest achievements is his contribution to the understanding of FRET (Förster resonance energy transfer). The term Förster radius, which is related to the FRET phenomenon, is named after him.[3] He also proposed the Förster cycle to predict the acid dissociation constant of a photoacid.[3] He also discovered excimer formation in solutions of pyrene.[3][5] WorkBook
