John Jeffries

John Jeffries (5 February 1745 – 16 September 1819) was a Boston physician, scientist, and a military surgeon with the British Army in Nova Scotia and New York during the American Revolution. He is best known for accompanying Jean-Pierre Blanchard on his 1785 balloon flight across the English Channel.

Jeffries is credited with being among America’s first weather observers. He began taking daily weather measurements in 1774 in Boston, as well as taking weather observations in a balloon over London in 1784. National Weatherperson’s Day is celebrated in his honor on 5 February, his birthday. The Archives and Special Collections at Amherst College holds a collection of his papers, including a letter he dropped from the balloon during his historic flight, considered the oldest piece of airmail in existence.
