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.
Crokinole
The earliest known crokinole board was made by craftsman Eckhardt Wettlaufer in 1876 in Perth County, Ontario, Canada. It is said Wettlaufer crafted the board as a fifth birthday present for his son Adam, which is now part of the collection at the Joseph Schneider Haus, a national historic site in Kitchener, Ontario, with a focus on Germanic folk art. Several other home-made boards dating from southwestern Ontario in the 1870s have been discovered since the 1990s. A board game similar to crokinole was patented on 20 April 1880 by Joshua K. Ingalls (US Patent No. 226,615)
