He Made it good for people who go to Radio City Hall. You don’t
have to freeze when you go there. You can have a Warm Christmas in
the Radio City Hall. Why?
Because of David Crosthwait: He was born in Nashville, Tennessee
and moved to Kansas City Missouri. David got a Bachelor of Science
degree in 1913 and Master of Engineering degree in 1920.
In 1913, Crosthwait moved to Iowa where he worked
for the Durham Company designing heating installations.
By 1925, he got the title director of the research department
leading a staff of both engineers and chemists.
Crosthwait’s research involved heating and ventilating and he
received 39 patents for a variety of devices like heating systems,
vacuum pumps, refrigeration methods and processes and temperature
regulating devices. One of David’s most famous creations is the
heating system for New York’s famous Radio City Music Hall.
