The Honeywell name is most often associated with thermostats, but the company known today as Honeywell International is the result of the takeover of Honeywell Inc. by the conglomerate AlliedSignal in 1999. The old Honeywell was a frequent target of antiwar protests during and after the Vietnam War because of its role in making deadly munitions such as fragmentation bombs. Responding to those pressures as well as financial problems within its defense segment, Honeywell announced in 1990 that it was spinning off most of its military operations into a new company called Alliant TechSystems.
The new Honeywell International is doing a substantial amount of work for the Pentagon, given the extensive aerospace operations that AlliedSignal brought to the marriage. Yet most of its customers are civilian industries that make use of its aerospace components, its automation and control systems, its specialty materials and its automotive parts.
AlliedSignal (previously Allied Chemical) saddled the combined company with a number of serious environmental messes that Honeywell has had to pay hundreds of millions of dollars to clean up.
