The Worshipful Company of Coopers is one of the Livery Companies of the City of London. The organisation of coopers existed in 1422; the Company received its first Royal Charter of incorporation in 1501. The cooper trade involved the making of wine, beer, and spirit casks (a barrel is specifically a 36-gallon cask, or 32 in some circumstances); the Livery Company also functions as a charitable foundation, and supports two education establishments the Coopers' Company and Coborn School of Upminster, Essex, and Strode's College of Egham, Surrey. The former was founded in the Ratcliffe area of London in 1536 and donated to the Company who have been involved with it ever since.
