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.
White cane
In the United States, the introduction of the white cane is attributed to George A. Bonham of the Lions Clubs International. In 1930, a Lions Club member watched as a man who was blind attempted to cross the street with a black cane that was barely visible to motorists against the dark pavement. The Lions decided to paint the cane white to make it more visible. In 1931, Lions Clubs International began a program promoting the use of white canes for people who are blind.
