Hymers College is a co-educational independent school located on the site of the old Botanic Gardens of Hull, East Riding of Yorkshire, England. It was established in 1893 as a boys' school, but expanded to include girls from the 1970s onwards. By his will of 24 August 1885, the mathematician John Hymers left some of his property to the mayor and corporation of Hull, to provide for the foundation of a grammar school, "for the training of intelligence in whatever social rank of life it may be found among the vast and varied population of the Town." An obscurity in the wording of the will rendered the bequest invalid, but his heir, his brother Robert Hymers, voluntarily granted the sum of £50,000 for the establishment of Hymers College, Hull. There has been a steady development of buildings and facilities. In recent years additional land has been purchased, a theatre (opened by and named after Dame Judi Dench), science laboratories, an all-weather sports pitch, and other sports facilities have been constructed. A new junior school has also been built. A swimming pool was added in 2005.
