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.
Flip chart
The earliest known patent of a flipchart is from May 8, 1913. Flip charts have being in use from the 1900s, the earliest recorded use of a flip chart is a photo from 1912 of John Henry Patterson (1844-1922), NCR’s CEO while addressing the 100 Point Club standing next to a pair of flip charts on casters. The flipchart we know (on a small whiteboard) was invented by Peter Kent in the 1970s. Peter Kent was the founder and CEO of the visual communications group Nobo plc, and it is believed that they were the first company to put the large pieces of paper over whiteboards, rather than over other materials.
