Truman's Brewery was a large East London brewery and one of the largest brewers in the world at the end of the 19th century. Founded around 1666, the Black Eagle Brewery was established on a plot of land next to what is now Brick Lane in London, E1. It grew steadily until the 18th century when, under the management of Benjamin Truman, and driven by the demand for porter, it expanded rapidly and became one of the largest brewers in London. Its growth continued into and through the 19th century with the expansion of its brewery and pub estate. In 1873, it purchased Philips Brewery in Burton and became the largest brewery in the world.
The situation changed for Truman's in the 20th century as it had to come to terms with the rise of lager, cheaper competition from imports and the consolidation of the biggest names in British brewing through mergers. Attempts to come to terms with these changes through management restructures and rebranding did not succeed, and in 1989 the brewery was closed.
The Truman's brand was revived in 2010 and, since 2013, beer is again being brewed in East London under the Truman's name.
The original Truman's brew house is generally claimed to have been founded in 1666. However, the historical evidence is not conclusive, with dates ranging from 1663 to 1669. What is clear is that the name came from Joseph Truman, who having previously worked in the brew house, took control of it in the 1680s. Truman’s grew under his stewardship, leading to the purchase of more land around the original site and Truman’s becoming a fully-fledged brewery. When he died in 1719, his eldest son, also called Joseph, initially succeeded Joseph Truman. However, within a few years control of Truman's passed to the younger son Benjamin Truman.
Truman's flourished under Benjamin Truman, a shrewd businessman blessed with good luck. The latter led to Truman's becoming the drink of the Royal Family. "When the Duchess of Brunswick was born in 1737, the Prince of Wales ordered four loads of faggots and a number of tar barrels to be burned before Carlton House to celebrate the event, and directed the Brewery to his household to place four barrels of beer near it for the use of those who chose to partake in the beverage, which certain individuals had no sooner done than they pronounced the liquid of inferior quality. This declaration caused a revolt: the mob threw the beer in each other’s faces and the barrels into the fire. The Prince had the good nature to order a second bonfire on the succeeding night and procured four barrels of beer from Truman ‘with which the populace was pleased and satisfied’".
