Air conditioning
In 1902, the first modern electrical air conditioning unit was invented by Willis Carrier in Buffalo, New York. After graduating from Cornell University, Carrier found a job at the Buffalo Forge Company. There, he began experimenting with air conditioning as a way to solve an application problem for the Sackett-Wilhelms Lithographing and Publishing Company in Brooklyn, New York. The first air conditioner, designed and built in Buffalo by Carrier, began working on 17 July 1902.
Bubble Wrap (brand)
Bubble wrap was invented in 1957 by engineers Alfred Fielding and Marc Chavannes in Hawthorne, New Jersey. Fielding and Chavannes sealed two shower curtains together, creating a smattering of air bubbles, which they originally tried to sell as wallpaper. When the product turned out to be unsuccessful as wallpaper, the team marketed it as greenhouse insulation. Although Bubble Wrap was branded by Sealed Air Corporation (founded by Fielding and Chavannes) in 1960, it was not until a year later that its use in protective usage was discovered. As a packaging material, Bubble Wrap's first client was IBM, which used the product to protect the IBM 1401 computer during shipment. Fielding and Chavannes were inducted into the New Jersey Inventors Hall of Fame in 1993. Sealed Air celebrated Bubble Wrap's 50th birthday in January 2010.
