Thorild Wulff (born 1 April 1877 in Gothenburg; died late August or early September 1917 in Northwest Greenland[1]) was a Swedish botanist and polar explorer.
He obtained his doctorate degree from Lund University in 1902 based on observation he had made during a Swedish-Russian geodesy expedition to Svalbard.
[2] Wulff was research assistant in horticulture ("Centralanstalten för försöksväsendet på jordbruksområdet") 1905–09, docent of botany at Stockholm University College 1909–13.
In 1911 he travelled to Iceland with his friend the author Albert Engström who gave an account of the journey ("Åt Häcklefjäll" 1913).
On the return trip, the expedition suffered from bad weather and insufficient supplies, resulting in casualties, one of them being Wulff.
