Albert Tullgren

Hugo Albert Tullgren (7 September 1874, in Stockholm – 1 July 1958) was a Swedish entomologist and arachnologist. The eponymous "Tullgren funnel" is a modified Berlese funnel, a device used to extract small insects and arthropods from soil samples.

Tullgren received his bachelor's degree from Uppsala University in 1899, and from 1902 worked as an assistant at the National Entomological Institute. From 1907 he was associated with the entomology department of the Centralanstalten för försöksväsendet på jordbruksområdet (Central Institute for Experimental Agriculture), of which, he became a professor in 1913. He received an honorary doctorate from Uppsala in 1932. He published on Swedish insects (1920) working along with Einar Wahlgren (1874–1963). He also wrote books on insects of gardens and those of importance to agriculture.

The jumping spider genus Tullgrenella was named in his honor by Cândido Firmino de Mello-Leitão.
