WASHINGTON, Feb. 22, 2012 /PRNewswire-USNewswire/ — Following is the daily Black History Month feature from the U.S. Census Bureau:
WEDNESDAY, FEBRUARY 22: DAVID CROSTHWAIT
Profile America for the 22nd day of Black History Month. Few people knew more about heating and air conditioning than David Crosthwait. When not many African-Americans did so, he had earned bachelor and masters degrees in engineering by 1920 and spent his entire working years improving the systems that make life easier for all of us today. He held 39 patents for heating systems, vacuum pumps, refrigeration methods and temperature regulating devices. His most famous job was designing the heating system for Radio City Music Hall and Rockefeller Center in New York City. In 1975 — the year before he died — Crosthwait was awarded an honorary doctoral degree from his old alma mater, Purdue University. There are 293,000 mechanical engineers in the U.S. today, just over 3 percent of them African-Americans. You can find these and more facts about the African-American population on the Web at www.census.gov.
