Because there was so much letter-writing while I was growing up in 1940s and 1950s Britain, every home had somewhere to store their stationery, important documents and letters and postcards received from friends and family. Older people still used the old portable desks, but younger households turned to a more modern solution - modern that is for the 1940s and 1950s. It was the bureau.
The bureau was a largish piece of furniture with a slanting lid which folded down to make a flat writing surface. This was at a height suitable for writing when a chair was drawn up under it.
The bottom half of the bureau was cupboards, bookshelves or drawers. My parents' bureau had shelves on which they stored a set of inherited encyclopaedia.
Bureaus like all furniture at the time were made of dark wood.
It was a sign of the times that bureaus belonged to the men of the house, although I am sure there must have been exceptions.
