AlliedSignal, Inc. was an American aerospace, automotive and engineering company, created through the 1985 merger of Allied Corp. and The Signal Companies. It purchased Honeywell for $14.8 billion in 1999, and adopted the Honeywell name and identity.

AlliedSignal was a member of the Dow Jones Industrial Average from 1985 until February 19, 2008.


The Allied Chemical & Dye Corporation originated with the 1920 merger of five chemical companies: Barrett Paving Materials (est. 1852), General Chemical Company (est. 1899), National Aniline & Chemical Company (est. 1917), Semet-Solvay Company (est. 1895), and the Solvay Process Company (est. 1881). The consolidation occurred with the backing of chemist William Nichols, who became concerned about dependence on the German chemical industry during World War I, and financier Eugene Meyer. It acquired the Eltra Corporation in 1979.[1]

The company renamed itself the Allied Chemical Corporation in 1958, then simply the Allied Corp. in 1981. Allied merged with the Bendix Corporation in 1983, beginning the company's involvement in aerospace.

The Signal Companies traced their history to the Signal Gasoline Company, founded by Samuel B. Mosher in 1922. It renamed itself to Signal Gas & Oil in 1928 to reflect its expanding businesses. By the 1950s, Signal was the largest independent oil company on the West Coast of the United States and Mosher held large stakes in American President Lines and the Flying Tiger Line. In 1964, Signal merged with the Garrett Corporation, an aerospace company. In 1967 they purchased Mack Truck for $85m US.[2] The combined company adopted "The Signal Companies" as its corporate name in 1968[2][3] and in 1974 sold its original Oil operations to Burmah Oil for $480m.[2]

The merger of Allied and Signal made aerospace the new company's largest business sector.[4] The combined company adopted the name Allied-Signal on September 19, 1985.[5] It dropped the hyphen to become AlliedSignal in 1993 to reinforce a one-company image and signify the full integration of all of its businesses.[4] On June 7, 1999 AlliedSignal acquired Honeywell for $14.8 billion and took its more recognizable name.[6]
