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.
List of Oval Office desks
President William Howard Taft constructed the first permanent West Wing to the White House, intending it to be the hub of his administration. Designed by Nathan C. Wyeth and completed in 1909, this wing included the first official Oval Office. On December 24, 1929, during President Herbert Hoover's administration, a fire severely damaged the West Wing. He reconstructed the part of the White House affected, including the Oval Office, reopening them later in his presidency.
