Aramark was founded as Davidson Brothers in 1936 by Davre and Henry Davidson. Davidson Brothers began by providing vending services to plant employees in the aviation industry in Southern California.

In 1959, Davre Davidson partnered with William Fishman to establish ARA (Automatic Retailers of America), which became publicly traded a year later in 1960.

In 1968, ARA provided services at the Mexico City Olympic Games, the first of 16 Games they have serviced, including Athens in 2004 and Beijing in 2008.

In 1969, ARA amended its name and became known as ARA Services, intended to reflect its growing range of businesses.

In 1983, Joseph Neubauer was elected CEO of ARA Services, and a year later, Neubauer led a group of executives to fend off a hostile takeover bid by coordinating a management buyout.

ARA Services changed its name again to its present name, Aramark, in 1994.
