"The multi-billion dollar complex of businesses known today as The Marmon Group began in 1953 when brothers Jay and Robert Pritzker acquired The Colson Corporation, then an ailing manufacturer with continuing sales of $3.5 million. Once Colson was restored to profitability, other small businesses were acquired or created. By the early 1960s, a dozen companies had joined informally to benefit from shared consulting and administrative services.
"In January 2002, Robert Pritzker concluded his five decade tenure at Marmon. Thomas Pritzker became Chairman and John Nichols was named Chief Executive Officer. The current decade has seen The Marmon Group organize into core business sectors dedicated to supporting growth in their respective industries. At the start of 2005, TransUnion, an information-based business that was unique within the largely manufacturing Marmon organization, was established as a stand-alone operation. In January 2006, Mr. Nichols became Vice Chairman of Marmon and was succeeded as CEO by Frank Ptak.
"In March 2008, Berkshire Hathaway Inc. acquired majority interest in The Marmon Group of companies."
