Rolf Martin Theodor Dahlgren (July 7, 1932 - February 14, 1987) was a Swedish-Danish botanist, professor at the University of Copenhagen from 1973 to his death.
Dahlgren was born in Örebro to apothecary Rudolf Dahlgren and wife Greta née Dahlstrand.[1] He took his MSc degree in Biology in (1955) and PhD degree in Botany in (1963) at Lund University.[2] He continued working on South African plants during expeditions in 1956-57 and 1965–66, while affiliated with the Botanical Museum in Lund as docent. In 1973, he became professor of botany at the University of Copenhagen. Here, he developed his system of Angiosperm classification, based on many more characters simultaneously than previous systems, most notably many chemical plant traits (see also chemotaxonomy). Although the system was first presented in Danish,[3] it rapidly gained widespread acceptance, particularly due to the instructive diagrams, socalled Dahlgrenograms. His work on family circumscription in the Monocotyledons, published with H. T. Clifford and Peter Yeo, has had profound influence well into the molecular age.[4][5] He was killed in a car crash in Scania, Sweden.[6] A Rolf Dahlgren Memorial Symposium was held in Berlin, Germany later in 1987. The couple had three children, Susanna, Helena and Fredrik.[7]
In 1986, he was elected member of Royal Swedish Academy of Sciences. The South African monotypic plant genus Dahlgrenodendron (J.H. Ross) J.J.M. van der Merwe & A.E. van Wyk was named to him honour in 1988[8]
