David Crosthwait Jr., transformed heating and air industry
WACO, Texas (Feb. 19, 2014) – Many African-American inventors have left their mark on society. Inventors like George Washington Carver, who transformed the way we look at peanuts, and Garret Morgan, who pioneered modern driving practices with the invention of the traffic signal, changed the world in many ways. One inventor, in particular, David Crosthwait Jr., transformed the heating and air conditioning industry.
Crosthwait invented the vacuum pump, a boiler, and a thermostat control, all for more effective heating systems for larger buildings. His inventions were instrumental to the heating and air conditioning trade.
He is known for creating the heating systems for both Rockefeller Center and Radio City Music Hall.
“David Crosthwait was a true pioneer in the heating and air conditioning business,” said Doyle James, president of Aire Serv. “Without his knowledge and skills we certainly would not be where we are today as an industry and trade.”
During his 56-year career in the heating and air conditioning business, Crosthwait held 119 patents in the heating and air conditioning industry.
Crosthwait was not only an inventor, he also wrote for the American Society of Heating and Ventilation Engineering Guide. In 1971 he was the first African-American to become a fellow of the American Society of Heating, Refrigeration and Air Conditioning
Crosthwait graduated from Purdue University, receiving a degree in mechanical engineering. After graduating he took a job with C. A. Dunham Company, specializing in product research and design, eventually becoming the Director of Research.
“David had a great career that brought us many great inventions,” said James. “It is hard telling where we would be today in our industry without his inventions and design abilities. He paved the way for our industry to grow and we are all thankful for what he has given us.”
