Mordechai Donowitz

Mordechai Donowitz, PhD., was a young professor at Transylvania Polygnostic University who is the Chair of the Department of Non-Humanities and Tampering Within God's Domain. He led a team of researchers into Castle Heterodyne and was subsequently captured by the Castle. Klaus later negotiated with the Castle and got him out.

He is the father of Hezekiah Donowitz, and his name and identity only appear in a footnote on page 35 of the print novel Agatha H. and the Voice of the Castle.
