Any history buff knows about the fantastic events that have shaped our world, there have been wars, evil dictators, messiahs, and natural catastrophes that are all documented in scores of history books. The Civil War is entirely the most written-about battle in American history with our 16th President Abraham Lincoln as the main character. There will constantly be historical topics to write about, however for the Civil War and other major events, finding modern pleased is like trying to find something undisturbed at a popular buffet near closing time. The pickings are quite thin, but fortunately for historical writers, there is a fresh smorgasbord of material with lesser-known events and people, but i’m sure there is some demand for literature about Martin Van Buren or Millard Fillmore, two of the more forgettable U.S. presidents. I’ve found our history niche with the development of refrigeration and Heating and Air Conditioning that, to me, begins with John Gorrie. The ill-fated dentist/inventor invented the first mechanical ice-making component in 1851. Interestingly, 9 years previous to the icemaker, Gorrie designed and built an air-cooling apparatus for treating red fever patients. It was the first known AC unit. In 1902 Willis Carrier became the “Abe Lincoln of AC history” when she introduced the first modern AC system, one little-known fact is that the term “cooling system” was coined by American engineer Stuart Cramer in 1906. The basic concept of AC and Heating and Air Conditioning has not changed however history will view the 1975s as a milestone. The decade saw Heating and Air Conditioning change from an industry that focused merely on providing comfort in the home, to 1 that would do it with less energy and in an eco-friendly way; New Heating and Air Conditioning-related technologies of today will entirely keep future Heating and Air Conditioning historians busy.
