Ovidiu Constantinescu

Ovidiu Constantinescu (1933 – January 23, 2012) was a Romanian mycologist known for his work on the taxonomy of the Peronosporales.

Biography

Constantinescu was born in Constanța in 1933. He first graduated military school before ultimately enrolling at the Biological Institute at Bucharest University in 1949.^[1] Traian Săvulescu, founder of the Institute, and his wife Alice advised Constantinescu while he was a student. Constantinescu graduated in 1970 from the Institute. Following his defense, he remained at the Institute as an assistant as well as the curator of the Mycological Herbarium there.^[1] In 1974, Constantinescu published a book, Metode și tehnici în micologie, which was his first book on methods in mycology.^[2] Although it was never translated from Romanian, for its time it was widely recognized as one of the best mycological methods books.^[3] After working for one year in 1982 at the Centraalbureau voor Schimmelcultures in Baarn, Netherlands, he moved to Sweden in 1984. He was hired at the Institute for Systematic Botany at the University of Uppsala. Because of his vast knowledge and expertise about members of the order Peronosporales, he began the university's culture collection, known as Mykoteket. Constantinescu dedicated the next 20 years building up the collection for the university. He remained in Sweden at Uppsala University for the rest of his life working on members of the family Peronosporaceae, describing six new genera to add to the family after none had been added for over 30 years.^[1] Constantinescu compiled and published an annotated list of over 500 species in the genus Peronospora in 1991.^[3] He is also known for describing new species of and working on downy mildew pathogens.^[4]
