Carl Bergquist was 29, a college graduate and former Army lieutenant, when he quit a corporate job in 1964 to strike out on his own.
Bergquist accepted a retiring neighbor's offer to take over as a manufacturer's representative for a line of electrical varnish.
"I didn't have a plan," recalled Bergquist, 79. "But my father, a baker in south Minneapolis, said if you're going try something and you go broke, do it when you're young. Not when you have a family. I had all of $300 in the bank."
Bergquist hedged his entrepreneurial instincts by staying on as a part-time night file clerk at Sheldahl.
Smart move. His first month's commission check was all of $32.
Last fall, 50 years later, he sold his privately held Bergquist Co. for $570 million to German industrial conglomerate Henkel.
"It's God's money, not mine," said Bergquist, who said he and his wife, Libby, plan to step up their anonymous philanthropy. "We have been so blessed."
Chanhassen-based Bergquist Co. had sales last year approaching $200 million and employs 1,000 people, most at five Midwest sites.
