Why Is Karl Olov Hedberg Influential?

(Suggest an Edit or Addition)

According to Wikipedia, Prof. Karl Olov Hedberg of Västerås was a botanist, taxonomist, author, professor of systematic botany at Uppsala University from 1970 to 1989, and an Editor of the Flora of Ethiopia. Career Professor Hedberg was a pioneer in scientific knowledge on the afroalpine vegetation. Our present knowledge of this biosystem owes much to the research he and his wife Inga did on the Rwenzori and other high mountains in East Africa. His breakthrough views were based on their systematic fieldwork in the late 1940s. 'Features of Afroalpine Plant Ecology' remains a landmark in equatorial alpine ecological research up till today, and is still available in a facsimile re-edition of 1995.
