David Crosthwait By: Mayur David Crosthwait made tremendous contributions to the design, installation, testing, and service of power plant and heating and ventilation systems. David Crosthwait was born in Nashville, Tennessee in 1898, and then grew up in Kansas City, Missouri. Crosthwait earned a bachelors degree from Purdue University in 1913, and in 1920, he got his masters degree in engineering. A few years later, he became Research Engineer, Director of Research Laboratories for C. A.
Dunham Company, in Marshalltown, Iowa. He worked there from 1925 to 1930. During the 1920’s and the 1930’s Crosthwait made many improved or new inventions like, an improved boiler, a new thermostat control and a new differential vacuum pump. All of those were used to improve performance in bigger buildings. He became known for finding solutions to heating and ventilation problems. He even designed the heating system in the Radio City Music Hall in New York City. Throughout his career, Crosthwait had got 39 U. S. atents, and 80 foreign patents, relating to the design, installation, and service of HVAC power plants, heating, and ventilation systems. He also made a manual on heating and cooling with water and guides, standards, and codes that dealt with heating, ventilation, refrigeration, and air conditioning systems. In 1956 the C. A. Dunham Company and the Bush Manufacturing Company merged to create the Dunham-Bush company. So, in 1913 Crosthwait moved to Iowa to work with them, and was a technical advisor of Dunham-Bush from 1930 to 1971.
While at Dunham, he conducted research in several areas, including heat transfer and steam transport. His work led to many innovations in HVAC devices and technology. Besides research, product development, and HVAC system design, Crosthwait also wrote articles and revising sections of American Society of Heating and Ventilation Engineers Guide. His accomplishments were recognized by many in engineering. He won a medal from the National Technological Association in the 1930 for his work. After retiring from his career in 1971, Crosthwait taught a course on steam eating theory and control systems at Purdue University during the 1970s. For his academic excellence, Crosthwait was awarded an honorary doctorate from Purdue in 1975. He was also a member of the AAAS, and he was also a member of the American Society of Heating, Refrigerating and Air Conditioning Engineers, the American Chemical Society, and the National Society of Professional Engineers. David Crosthwait died in 1976. He made tremendous contributions to the world of science, by perfecting manuals, writing books, and discovering new innovations for ventilation systems.
He made numerous contributions to the world of heating and ventilation, by improving the design, installation, testing, and service of power plant heating, and ventilation systems. Crosthwait was honored with the role of designing the heating system Radio City Music Hall in New York City. Those are the numerous, and astounding contributions that David Crosthwait made.
