| 説明 | "An open letter to the HVACR industryLarry ClarkOur company, as successor to the original C.A. Dunham Co. (later Dunham-Bush) and heir to that company's rich history, frequently receives inquiries for information regarding our founder. The Dunham and Dunham-Bush names are, of course, widely recognized worldwide in our industry. And many of you know the story of how, just after the turn-of-the-century, a young engineer at the Iowa Soldier's Home--Clayton A. Dunham--became frustrated with the steam technology then available. So he began working in Dave Lennox's workshop in Marshalltown, IA (where, incidentally, Lennox built the first riveted-steel furnace, starting his company on the way to becoming the HVAC giant Lennox Industries of today, and industry leader Fisher Controls was also born). Dunham developed the first successful thermostatic steam trap in 1903 and started the C.A. Dunham Co.However, it was another individual, not nearly as well known outside of academia, who significantly contributed to the growth and success of the Dunham Co. and to the development of steam heating technology. After 20 years of growth and prosperity, Clayton Dunham wrote to Purdue University, telling them that he wanted to hire their top engineering student "sight unseen" In 1925, David Nelson Crosthwait, Jr., who had received both his B.S. and Masters of Engineering from Purdue, stepped off the train at the Marshalltown station to be welcomed by Dunham and thereby become the first black American to live and work in the town.For the next five years, Crosthwait served as director of Research Laboratories for the C.A. Dunham Co. and received 39 HVAC-related U.S. patents. For the next 41 years, from 1930 to 1971, he served as technical advisor to the company, which by now had become Dunham-Bush, Inc. He then returned to his alma mater to teach steam heating theory and control. He received an honorary Doctorate from Purdue in 1975 and died in 1976. Although widely regarded as one of American's 25 most notable black scientists, with 80 international patents, he is perhaps best known for his design of the heating system for Radio City Music Hall in New York City. He is, however, virtually unknown outside of the scientific community.We at Marshall Engineered Products Company (MEPCO) believe that Dr. Crosthwait should be recognized by the HVACR industry for these accomplishments and it is to that end that we take great pride in sharing this brief synopsis of his life. To learn more, we invite you to read African American Inventors, Otha Richard Sullivan, Jim Haskins (Ed.), Wiley, John & Sons, Inc., 1997, and American Men and Women of Sciences, 12th ed., Bowker Co., 1971.Larry ClarkPresidentMarshall Engineered Products Co.Grand Rapids, MICOPYRIGHT 2006 Business News Publishing Co.COPYRIGHT 2006 Gale Group"FindArticles - An open letter to the HVACR industryEngineered Systems, Jan, 2006, by Larry Clark |
