P. G. Krolmeister is the owner and founder of Krolmeister industries.

In The Phantom of Venice, Helena Berg writes about him in her notebook, saying: Fabulously wealthy, yet insists on wearing ill-fitting pink jerseys and hosting waste-of-time poetry slams. Always invited to best parties - plays the token German intellect. Adore his fascination with Schiller and monkeys!

Trail of the Twister Edit

in 2010, P. G. hires Nancy to investigate some failing new equipment. Nancy can call him during the game.

Joe comments that P. G. must be at least 100 years old.

When Nancy discovers the culprit of the hijacks, he sends her on a trip to Japan, where she discovers the case of the Shadow at the Water's Edge.
