Whiteboard
Albert Stallion invented whiteboards while working at Alliance in the 1960s. Alliance (now known as PolyVision) produced enameled steel for architectural cladding, but Stallion noted it could also potentially be used as a writing surface. Stallion later left Alliance to form his own whiteboard production company, MagiBoards.
Bathtub hoax
On December 28, 1917, an article titled "A Neglected Anniversary" by H. L. Mencken was published in the "New York Evening Mail". It claimed that the bathtub had been introduced into the United States as recently as 1842, the first ones having been made of mahogany lined with lead. The article went on to describe how the introduction of the bathtub was initially greatly discussed and opposed until President Millard Fillmore had a bathtub installed in the White House in 1850, making the invention more broadly acceptable.
