July 31, 1790. On this date, just 14 years after the United States was born as a nation, the U.S. issued its first patent. It went to Samuel Hopkins, an inventor who resided Pittsford, Vermont, and later of Pittsford, New York. Hopkins discovered of a new method of producing potash and pearlash. The Carnegie Library of Pittsburgh explains:
Potash was the designation of a crude form of potassium carbonate derived as residue from the repeated boiling of wood ashes in a cauldron (or in 18th century parlance, a pot—hence, the name “potash”). Potash or the more refined pearlash may rightly be thought America’s first industrial chemical because this substance was an essential ingredient in the making of soap, glass and gun-powder.
Bottom line: The first U.S. patent was authorized in New York City, then the capital of the new country, on July 31, 1790. It went to Samuel Hopkins, an inventor who discovered of a new method of producing potash and pearlash, which could be considered as some of the first industrial chemicals.
Elizabeth Howell is an award-winning Canadian journalist who can't stop talking about space and science. As a teenager, she saw the movie Apollo 13 and wanted to be an astronaut. That hasn't happened - yet - but at least she gets to write about them. Elizabeth's favourite career moments so far include attending three shuttle launches, and legitimately writing the word "snot" into a Mars Curiosity story. Besides EarthSky, you can read Elizabeth's work in SPACE.com, Universe Today, SEN.com, All About Space and other fun places. Elizabeth's space obsession extends to her hobbies; she's a big fan of Battlestar: Galactica and has met all five TV Star Trek captains. She even visited Captain Kirk's future birthplace in small-town Iowa.
