History

In 1913, Parker B. Francis founded the predecessor to Puritan-Bennett, originally incorporated as Oxygen Gas Company, which was a manufacturer and distributor of oxygen and hydrogen. In 1920 the company changed its name to the Kansas City Oxygen Company and then again in 1931 to Puritan Compressed Gas Corporation as it continued to expand. In 1940, V. Ray Bennett and Associates, Inc was founded by Ray Bennett in Santa Monica, CA. In 1945 Bennett applies for a patent for the BR-X2 ventilator developed during WWII for delivery of intermittent positive pressure ventilation to pilots after he witnessed several crashes caused by pilots passing out in unpressurized aircraft at high altitude. He would later invent a

machine. V. Ray Bennett and Associates, Inc was acquired by Puritan in 1956 and the next year the company was renamed Bennett Respiration Products, Inc. By the 60's the company had added products such as the bubble jet and a heated humidifier to its oxygen therapy line. In 1967 Puritan released the MA-1 Volume Ventilator, an invention of Bennet's. This virtually replaced the cumbersome iron lung and made Bennet and Puritan recognizable names in the larger medical equipment field. This allowed the company to grow even more as they targeted international markets. In 1968 the parent company reorganized itself as the Puritan-Bennett Corporation and consolidated its medical marketing department into a single unit. In 1995, Nellcor acquired Puritan-Bennett and the newly expanded company was renamed Nellcor Puritan Bennett. In 1997, Nellcor Puritan Bennett became a part of
