Irwin Jacobs was a voluble, larger-than-life entrepreneur who built a fortune in the 1980s stalking, buying and selling some of the nation's largest companies.
While his successes made him a name on Wall Street for a time, he began and ended his six decades in business as a trader of everyday goods.
The bodies of Jacobs, 77, and his wife of 57 years, Alexandra, were found Wednesday in their Lake Minnetonka-area home, a friend calling the deaths a murder-suicide.
His name had faded in prominence in recent years, but for much of his career Jacobs was a feared and flamboyant investor, having risen to fame in the 1980s heyday of individual corporate raiders.
"He was a visionary. He was a taskmaster. He wasn't afraid of tough decisions," said Mark Sheffert, an executive in the 1980s at what is now U.S. Bancorp.
Jacobs once had a fortune valued at nearly $400 million in the 1990s. He took over and broke up the conglomerate AMF and made unsuccessful takeover runs at several other major companies, including Disney, Kaiser and ITT.
For a time, he also owned a minority stake in the Vikings.
With a series of deals that began in the 1970s, his Genmar Holdings Inc. became the nation's second-largest maker of boats by the 1990s. The firm downsized after the 2008 recession and underwent a lengthy bankruptcy restructuring.
