Cerberus Capital Management, L.P. is one of the largest private equity investment firms in the United States. The firm is based in New York City, and run by 49-year-old financier Steve Feinberg. Former U.S. Vice President Dan Quayle has been a prominent Cerberus spokesperson and runs one of its international units.

Founded in 1992, Cerberus is named for the mythological three-headed dog that guarded the gates of Hades. Feinberg has stated to his employees that while the Cerberus name seemed like a good idea at the time, he later regretted naming the company after the mythological dog.

The company has been a very active acquirer of businesses over the past several years and now has sizable investments in automotive, sportswear, paper products, military services, real estate, energy, retail, glassmaking, transportation, and building products. In 2006, its holdings amounted to $24 billion.
