Sir Edward Thomason (c. 1769 – 29 May 1849) was a manufacturer and inventor in Birmingham knighted by King William IV.
He was born around 1769 in Birmingham. His father Edward Thomason (1740 – 1793) was a manufacturer of buckles, and his mother was Mary Garlick.
He married Phillis Brown Glover, daughter of Samuel Glover of Abercarn, Monmouth, on 26 August 1799. His son, Henry Botfield Thomason, died on 12 July 1843 aged 41. Edward Thomason's grandson, and Henry Botfield's son, Henry Richard Yeoville Yardley Thomason became an architect in Birmingham, designing many of the city's landmark buildings.
At age 16 he was articled to Matthew Boulton in the Soho Foundry. He began manufacturing in his father's factory around 1793, establishing a trade in gilt and plated buttons. The business expanded into manufacture of medals, tokens and coins, and later plated gold and silver works. In 1835 he sold the business to Whitegrave and Collis.
In 1839 he improved the gun lock by making the cock detachable by the thumb and finger as well as making improvements to prevent misfires.
In 1844 he retired from business and moved to Ludlow, then Bath, then Warwick.
In 1845 he published his memoirs in which he illustrated his manufactured products and inventions.
He died in his house in Jury Street, Warwick in 1849, and a memorial was erected to him in St Philip's Cathedral, Birmingham.
In 1818 he was elected to the office of High Bailiff of Birmingham. He was also Vice-consul for the town of Birmingham for the governments of Russia, France, Prussia, Austria, Spain, Portugal, Brazil, Sweden and Norway.
