Minneapolis-Honeywell Regulator Company
In 1904 a young engineer named Mark Honeywell, was perfecting the heat generator as part of his plumbing and heating business. Two years later, he formed the Honeywell Heating Specialty Company, specializing in hot water heat generators.

By 1912, EHR had expanded its product line and changed its name to Minneapolis Heat Regulator Company. Four years later, MHR patented the first electric motor approved by Underwriters Laboratories.

In 1927, Minneapolis Heat Regulator Company and Honeywell Heating Specialty Company merged to form the Minneapolis-Honeywell Regulator Company, and became the largest producer of high-quality jeweled clocks. W. R. Sweatt became chairman and Mark Honeywell, president. The company made several acquisitions in the controls area. One of those acquisitions was the Brown Instrument Company, a worldwide leader in the field of industrial controls and indicators, and inventor of the pyrometer. Until Edward Brown had invented the carbon-rod pyrometer in the mid-nineteenth century, there was no accurate way to measure the extremely high temperatures in foundries and kilns.

Minneapolis-Honeywell Regulator Company leveraged its scientific and engineering talent to transform itself and adapt to changing times. Mass production was perfected and an array of aeronautical equipment broadened the company's product portfolio. In 1942, the company invented the electronic autopilot (C-1), which proved to be critically important to the U.S. war effort.

In 1953, the company introduced the T-86 "Round" thermostat, which replaced chunky, rectangular models. One of the world's most recognizable designs, it remains in production today and adorns the walls of more households around the world than any other thermostat.

In 1954, the company acquired Doelcam Corp., a maker of gyroscopes. Over the next two decades, the company constantly improved gyroscopes, making them more sensitive and precise while reducing their size and weight. In 1955, a joint venture called Datamatic Corporation, was established with Raytheon Corp. that marked Honeywell's entry into the computer business. The company's first computer system, the D-1000, weighed 25 tons, took up 6,000 square feet and cost $1.5 million.

In 1957, Minneapolis-Honeywell Regulator Co. purchased a fire detection and alarm firm, the first of many acquisitions that would build its security business into today's global leader. In many North America cities, the red and black "Protected by Honeywell" window stickers and placards became nearly as recognizable as the Round thermostat.

Raytheon's interest in the computer venture was bought out in 1960 and the business name changed to Electronic Data Processing (EDP).

The company's name was officially changed to Honeywell Inc. in 1963, even though it had been casually referred to as such for nearly 40 years. Six years later, Honeywell instruments helped U.S. astronauts Neil Armstrong and Edwin "Buzz" Aldrin land on the moon.

In 1970, Honeywell merged its computer business with General Electric's to form Honeywell Information Systems, which performed well in mainframe markets. In 1986, the personal computer emerged and the company formed Honeywell Bull, a global joint venture with Compagnie des Machines Bull of France and NEC Corporation of Japan. Its ownership level was gradually decreased until, in 1991, Honeywell was no longer in the computer business. The digital computer knowledge was then applied to its traditional field of automation control, integrating sensors and activators.

In 1986, Honeywell significantly enhanced its position in the aerospace industry with the purchase of Sperry Aerospace. It instantly became the world's leading integrator of avionics systems. Sperry contributed flight controls, space vehicles and the first FAA-certified wind shear warning system.
