A brownie, brounie/Urisk (Lowland Scots) or ùruisg/brùnaidh/gruagach (Scottish Gaelic) is a legendary kind of elf or fairy popular in folklore around Scotland and England (especially the north). It is the Scottish counterpart of the Scandinavian tomte, the Russian domovoi or the German Heinzelmännchen.
Brownie was the name of a long-running and extremely popular series of simple and inexpensive cameras made by Kodak. The Brownie popularized low-cost photography and introduced the concept of the snapshot. The first Brownie, introduced in 1888, was a very basic cardboard box camera with a simple meniscus lens that took 2¼-inch square pictures on 117 rollfilm.
Brownie was the affectionate name to a Fender Stratocaster that was used extensively by Eric Clapton during the early 70's most notably with Derek and the Dominos on their album Layla and Other Assorted Love Songs.
An imaginary good-natured spirit, who was supposed often to perform important services around the house by night, such as thrashing, churning, sweeping.
