Paul Rosenius

Johan Anders Martin Paul Rosenius (12 March 1865 – 5 July 1957) was a Swedish physician, ornithologist, artist and writer.

He studied gastrointestinal diseases at the Sahlgrenska hospital in Gothenburg and worked with Dr J. Boas in Berlin and made a trip to Vienna before moving to Malmö to practice privately from 1895.

Their circle of radical thinkers known as the De unge gubbarne or DUG held debates including a prominent one on ethics from an evolutionary perspective, in which Lidforss took part on March 9, 1888.

They had a son Bengt and a daughter Karin, who married George Felix Allen Skelton (1909-1985),[4] an English RAF pilot whose Defiant was shot over the Netherlands in 1940.

[5] Skelton had been held prisoner in Germany during World War II and Rosenius was able to influence his extradition in 1943 in exchange for a bound set of his volumes on Swedish birds and their nests sent to Hermann Göring.
