#DidYouKnow – John Jeffries?

American’s First Weatherman

#DidYouKnow is a Blog Series on www.jmnorthup.com and www.nornstriad.com

John Jeffries was an American physician (who graduated from Harvard) and balloonist (one of the first to cross the English Channel) who lived from 1745 until 1819. He is noted to be among the first Americans to start logging daily weather measurements, starting in 1774. His work set the precedent of our national model for weather record-keeping and has earned him the title as America’s First Weatherman.

On January 7, 1784, John Jeffries joined Jean-Pierre Blanchard in a hot air balloon, earning John fame as the First American Balloonist to cross the English Channel. During the flight, “he carried a thermometer, a barometer, and a hygrometer to the height of 9,000 feet.” In addition, he took “seven small bottles for obtaining samples of air at different heights.” A true meteorologist at heart!
