Heinrich Anton Müller (22 January 1869, Versailles – 10 May 1930, Münsingen) was a Swiss outsider artist and painter.
Müller married a Swiss woman and moved to the canton of Vaud to become a winegrower.
While working in wine, he invented and patented a grapevine trimming machine, which would later influence his art.
[2] Müller was then institutionalized in a Münsingen psychiatric hospital at 37 years old until his death at age 61.
In there, he began creating "machines" on hospital grounds that were mostly made of wires, discarded wood, and strips of cloth while being glued together by his own excrements.
