Henni Lehmann

Her father, Wolfgang Straßmann, was a doctor and social activist who, for many years, was a member of the Prussian House of Representatives.

[1] In 1888, while attending the Royal School of Art, she met and married Karl Lehmann [de], a legal scholar.

Disturbed by the living conditions she found nearby, in 1913 she gave the islanders a loan to build a medical facility and, in 1914, became a founder and board member of the local "Natur- und Heimatschutzbundes" (Nature and Home Protection Confederation).

[2] In 1920, she bought an old fachhallenhaus in Hiddensee and converted it to an art exhibition venue that was dubbed the Blaue Scheune (Blue Barn), after the color she chose for the exterior.

Her death is generally believed to have been a suicide;[1] possibly in response to the news that her daughter was dying of cancer.
