Biography


Mie was born in Rostock
Rostock
Rostock -Early history:In the 11th century Polabian Slavs founded a settlement at the Warnow river called Roztoc ; the name Rostock is derived from that designation. The Danish king Valdemar I set the town aflame in 1161.Afterwards the place was settled by German traders...

 at Martin Luther University of Halle-Wittenberg. In 1924 he became Professor at the University of Freiburg, where he worked up to his retirement in 1935.

In Freiburg, during the Nazi dictatorship, Mie was member of the university opposition of the so-called "Freiburger Kreis" (Freiburg circle) and one of the participants of the original "Freiburger Konzil".

He died at Freiburg im Breisgau in 1957.
