Founded in 1954, The Marmon Group is unique among American corporations. Privately owned by the Pritzker family, The Marmon Group is an assembly of more than 130 loosely affiliated companies, including such consumer stalwarts as TransUnion. This diverse group was built through acquisition, many of which were engineered by Jay Pritzker, who today is considered one of the geniuses of corporate acquisition. After they were purchased, management of the Marmon Group member companies fell to Jay's younger brother, Bob Pritzker, who was the head of The Marmon Group for the first fifty years. The Marmon Group: The First Fifty Years tells the interesting insider's story of building one of America's largest privately owned corporations.
