Marquardt Corporation

Marquardt Corporation was an aeronautical engineering firm started in 1944 as Marquardt Aircraft Company and initially dedicated almost entirely to the development of the ramjet engine. Marquardt designs were developed from the mid-1940s into the early 1960s, but as the ramjet disappeared from military usage, the company turned to other fields.

In 1968 Marquardt was merged with CCI Inc. of Tulsa, OK. The newly merged firm became known as "CCI-Marquardt, Inc.". That name changed back to "CCI Inc." after a few years. Throughout the 1970s and 1980s pieces of Marquardt were sold off or merged with other firms. By the 1990s, one of the remnants of the company, called ''Marquardt Manufacturing Inc.'' (MMI) was embroiled in a legal suit with its predecessor organization, which had become principally a landlord who owned the buildings and land where MMI was located. By then, most of the remaining pieces of Marquardt were part of Ferranti in England which was in bankruptcy. MMI subsequently declared bankruptcy and sank into oblivion. The remaining piece, ''Marquardt Jet Laboratories'' was sold to Kaiser Aerospace. Kaiser-Marquardt was later sold to Primex in Florida. Primex finally became part of Aerojet Rocketdyne.
