Ludwig Binswanger entered the world on the 13th of April 1881 in Kreuzlingen, Switzerland. His father Robert Johann Binswanger ran the Bellevue Sanatorium which his grandfather Ludwig Elieser Binswanger founded in 1857.
Binswanger received his medical degree from the University of Zurich in 1907. That same year he visited Sigmund Freud alongside Carl Jung and joined the early Freud Group led by Jung in Switzerland.
From 1911 to 1956 he served as medical director of the sanatorium in Kreuzlingen. He published his 1942 book Grundformen und Erkenntnis menschlichen Daseins to explain this new approach during that period.
Binswanger studied a deeply troubled patient named Ellen West for decades before publishing her case in his 1957 book Schizophrenie published by Pfullingen. Modern observers often suggest she suffered from anorexia nervosa instead of the schizophrenia diagnosis he provided.
Binswanger identified three modes of existence called Umwelt, Mitwelt, and Eigenwelt to explain human experience. The Umwelt refers to the around world shared with non-human animals while the Mitwelt describes the with world involving inter-species relations among humans.
