Harris Corporation
The "Harris Automatic Press Company" was founded by Alfred S. Harris in Niles, Ohio, in 1895. The company spent the next 60 years developing lithographic processes and printing presses before acquiring typesetting company Intertype Corporation. In 1957, Harris acquired Gates Radio, a producer of broadcast transmitters and associated electronics gear, but kept the Gates brand name alive by putting the Gates sticker on the back of numerous transmitters that were labeled Harris on the front panels.
Melpar
Some employees left Melpar to start new companies (usually in the Washington area). Over the next 20 to 30 years more than a dozen spin-offs generated millions of dollars in annual sales and employed thousands in the Washington area. One employee began a communications company in Florida that ultimately became the Harris Corporation. 
Two employees from a research division near Boston formed the data communications manufacturer Codex Corporation in 1962.
. Many prospered in the 1970s and 1980s, but then left the area, due to industrial consolidations, mergers, and acquisitions. Meloy Laboratories continued Melpar's biotechnical, pharmaceutical research until Rhône-Poulenc moved the operation to Philadelphia in the 1980s. A flight simulator spin-off named Simulation Engineering Corporation (Secor), went through four changes in ownership in Northern Virginia–from Sperry Rand to Honeywell to Hughes to Raytheon - before being moved to Texas in 1998. The same employees started a second company, Quintron, which was purchased by Loral for $22 million and later owned by Lockheed. A few companies still reside in Northern Virginia –VSE Inc in Alexandria (1300 employees), RSI Inc in Sterling (500 employees), ISOMET in Springfield, ST Research (now a division of Boeing called Argon ST) in Newington, as well as half a dozen small machine shops.
