In 1941 engineer Carl Kronmiller and industrial designer Henry Dreyfuss created a round-shaped home thermostat. The project, however, was shelved because of World War II. The Round was introduced to the public in 1953, when Minneapolis-Honeywell was seeking a new product to increase sales.
The T-86 Honeywell Round thermostat — known simply as The Round — was easy to make, easy to use, and easy to identify. Sales to both contractors and homeowners soared.
In 1963 the company’s name changed to Honeywell.
