Ipswich Museum is a registered museum of culture, history and natural heritage located on High Street (off Crown Street) in Ipswich, the County Town of the English county of Suffolk. It was historically the leading regional museum in Suffolk, housing collections drawn from both the former counties of East Suffolk and West Suffolk, which were amalgamated in 1974.
The original foundation of 1846, devoted primarily to Natural History, was moved to new premises in High Street in 1881. In about 1895 Christchurch Mansion, a large 16th-century house near the town centre in Christchurch Park, was given to the town. It was developed as a second venue under the same management and curatorship, devoted particularly to fine and decorative arts. Both are parts of one institution and draw on the same central core of collections. The entire service was merged with that of Colchester (Essex) on 1 April 2007 under management from Colchester.
The museum was founded in 1846 and opened in December 1847 in Museum Street, Ipswich then newly laid-out, with the specific remit to educate the working classes in natural history. From 1847 to 1853 it was run by a committee on behalf of subscribers, with open evenings for the public. The first President was the entomologist William Kirby (1759-1850), an original Fellow of the Linnean Society, and its founding Patron was Bishop Stanley of Norwich, who presided at the opening. The first Curator was Dr. William Barnard Clark: following his resignation in 1850 he was replaced by Mr David Wooster.
The primary initiative for this philanthropic venture came from George Ransome, FLS, a member of the Quaker Ransome family of Ipswich and younger brother of (James) Allen Ransome. The Ransome engineering industry helped to build the town's industrial prosperity in the early 19th century. All political complexions became involved in the common aim of social improvement through the Museum, and over sixty leading scientists lent their support as Honorary Members or Vice-Presidents.
