Carl Louis Ferdinand von Lindemann
* 12.4.1852 (Hannover) - † 6.3.1939 (München)
seine ersten Lebensjahre. 1882 ergab sich aus seinen Untersuchungen der Kreiszahl π, daß die Quadratur des Kreises mit Zirkel und Lineal nicht möglich ist. Damit löste er eines der ältesten mathematischen Probleme.

(English Translation)
The mathematician Carl Louis Ferdinand von Lindemann, born on April 12, 1852, in Hannover and died on March 6, 1939, in Munich, spent his earliest years here at the former Langestraße 26. In 1882, his investigations into the number π established that squaring the circle with a compass and straightedge is impossible. He thereby solved one of the oldest mathematical problems.

Carl Louis Ferdinand von Lindemann (12 April 1852 – 6 March 1939) was a German mathematician who proved in 1882 that π (pi) is a transcendental number, meaning it is not a root of any nonzero polynomial with rational coefficients.
