Bernd Ulmann is a professor for business informatics at the FOM (Frankfurt/Main). He studied mathematics at the Johannes Gutenberg University Mainz with philosophy as his minor. He wrote his diploma thesis about cryptographically secure pseudorandom number generators and his Ph.D. thesis at the University Hamburg about analog computing, the field he is obsessed with (to quote his wife and friends). He devotes his leisure time to collect and restore historic analog computers and devise modern analog computers, and loves programming both of them.
