Rudolf Weyrich

Rudolf Weyrich (1894 – 1971) was a German mathematician, physicist, and inventor.

Biography

Weyrich studied at the University of Rostock and at the University of Breslau, where he received in 1922 his Promotion (Ph.D.) under Adolf Kneser.[1] From 1923 to 1925 Weyrich was a Privatdocent at the University of Marburg.[2] In 1925 he became a professor extraordinarius at the Deutsche Technische Hochschule Brünn.[3] He worked there until 1945 when the Hochschule was abolished as part of the expulsion of ethnic Germans from Czechoslovakia. From 1948 to 1950 Weyrich was a lecturer at the Braunschweig University of Technology. In 1950 he was appointed a professor ordinarius at Istanbul Technical University, where he taught until his retirement in 1958. In retirement he lived in Braunschweig.[2]

Rudolf Weyrich ... served in World War I, was wounded at Brzeziny, and had consequently lost the sight in his left eye.[4]

Weyrich was an Invited Speaker of the ICM in 1932 in Zurich.[5]

gollark: Now, part of that is probably that you can't really trust whoever is asking to use those resources properly, and that's fair. But there are now things for comparing the effectiveness of different charities and whatnot.
gollark: But if you ask "hey, random person, would you be willing to give up some amount of money/resources/etc to stop people dying of malaria", people will just mostly say no.
gollark: If you *ask* someone "hey, random person, would you like people in Africa to not die of malaria", they will obviously say yes. Abstractly speaking, people don't want people elsewhere to die of malaria.
gollark: Capitalism is why we have a massively effective (okay, mostly, some things are bad and need fixing, like intellectual property) economic engine here which can produce tons of stuff people want. But people *do not care* about diverting that to help faraway people they can't see.
gollark: Helping people elsewhere does mean somewhat fewer resources available here, and broadly speaking people do not actually want to make that tradeoff.
