Whiteboard
Whiteboards became commercially available in the early 1960s, but did not become widely used until 30 years later. Early whiteboards needed to be wiped with a damp cloth and markers had a tendency to leave marks behind, even after erasing the board. Dry-erase markers for whiteboards were invented in 1975.
Sideboard (Edward William Godwin)
Godwin designed the first version of this sideboard in ebonised deal, a cheap wood, in 1867. He subsequently changed to ebonised mahogany, as he found deal to be unstable. At least ten versions of the original were made between 1867 and 1888, with differences in design, in decoration or in the number of legs. There are several surviving examples of this sideboard, made of ebonised deal, mahogany, or oak and pine. The original sideboard was designed by Godwin for the dining room of his London home in 1867.
