David Crosthwait

Managing Real Estate Broker with Fathom Realty PB00068179

David Crosthwait was born in Nashville, Tennessee back in 1898. At a young age the family moved to Kansas City, Missouri where he attended school. He received his Bachelor of Science and a Masters of Engineering degree from Purdue University.

His expertise was air ventilation, central air conditioning and heat transfer. He held 39 United States patents and 80 international ones. He invented a vacuum pump, a boiler and thermostat control devices. He retired in 1971, when he returned to Purdue to teach a course on steam heating and control systems. He died in 1976, he was 77.

What you may not know about David is that he created the heating systems for the Rockefeller Center and New York’s Radio City Music Hall. Such an accomplishment for an African-American back then, don’t you think? I can’t confirm it, but as far as I can tell his system is still in use to this day.

Your day is worthwhile when you make someone smile, so give the free gift of a smile today

Good morning, James - it's great to see the world of innovation, invention and other ingenious thinking is alive and well in our world.  It's good to see that David returned to his alma mater to teach and share his knowledge after he retired.

Good morning James,

Quite the accomplishment and in the winter would be at a disadvantage probably without his patents.

Make yourself an astonishing day.
