Vitus Grummann

Vitus Johannes Grummann (3 March 1899 – 12 December 1967, Berlin) was a German lichenologist and primary school teacher. Born in Jacobsdorf, Silesia, Grummann began his career in education and served as a primary school teacher in the Berlin area for many years. His professional path took a turn when he started studying natural sciences at the Friedrich-Wilhelm University, developing a fascination with botany, especially lichens. He earned his doctorate in 1939, producing a dissertation on morphological deviations in lichens. After World War II, Grummann headed a department at the Reich Institute for Film and Picture in Science and Education and simultaneously taught at Berlin high schools. His academic career was distinguished by 18 publications on various floristic projects and the creation of a comprehensive biographical-bibliographical handbook of lichenologists worldwide. Grummann also took an active interest in the works of Silesian artists and authors. Several lichen species were named in his honour in recognition of his contributions. Provided by Wikipedia
