Elsa Nyholm

Elsa Cecilia Nyholm (née Tufvesson) (1911–2002) was a Swedish botanist, in particular bryologist, and researcher at Lund University and the Swedish Museum of Natural History.

Elsa Nyholm was born at a farm a in Nordanå in rural Scania, southernmost Sweden. Despite a strong interest in natural history, she was not allowed to attend grammar school. Instead, she went to handicraft and household schools and developed her interest in nature on the side. In 1932, she got a job as museum assistant at the Lund University botanical museum. There, she specialized in bryology and conceived the idea of a grand moss flora of Northern Europe. Although lacking a formal academic degree, she found support at the Swedish Museum of Natural History in Stockholm and received research council grants from 1954 to 1964 to undertake the work. From 1964 to her retirement, she was the head curator of the moss herbarium at the Swedish Museum of Natural History.

Elsa Nyholm's name is particularly associated with her two grand moss floras, the Illustrated Moss Flora of Fennoscandia and Illustrated Flora of Nordic Mosses. She had a lasting and fruitful collaboration with the British bryologist Alan Crundwell.

The bryophyte genus Nyholmiella (Orthotrichaceae) is named in her honour.
