W. & R. Chambers
- Founded in circa 1819.
- Founded by the two brothers William Chambers of Glenormiston and Robert Chambers. They were born into a rich, mill-owning family in Peebles in Scotland in 1800 and 1802 respectively, during the time of the war with France. The war impoverished the family and, in 1813, the family left Peebles for Edinburgh.
