Conrad was born in either
Mainberg or Mebenburg, both in Bavaria. He was born on 2 February 1309. Conrad himself calls his native place Megenberg, hence continued confusion on his birthplace. He studied at Erfurt and the University of Paris; at the latter university he obtained the degree of Master of Arts, and he taught philosophy and theology at the University of Paris for several years.
By 1337 he was living in Vienna. That year he became head of St. Stephen's school. He relocated, in 1342, to Regensburg. There, he became a priest, then a preacher, and eventually a cathedral canon. He was also a member of the local town council. In 1357 he made a journey to the Papal Curia in 'Babylonian exile' at Avignon. He died at Ratisbon (and alternative name for Regensburg) on 11 April 1374.
