The Foundling Museum in London tells the story of the Foundling Hospital, Britain's first home for abandoned children. The museum houses the nationally important Foundling Hospital Art Collection as well as the Gerald Coke Handel Collection, the world's greatest privately amassed collection of Handel memorabilia.
The museum examines the work of the Foundling Hospital's founder Thomas Coram, as well as the artist William Hogarth and the composer George Frideric Handel, both major benefactors of the institution. It also illustrates how the Foundling Hospital's charity work for children still carries on today through the child care organisation Coram.
The Foundling Museum was set up as a separate charitable organisation in 1998. After a major building refurbishment it opened to the public as a state-of-the-art museum in June 2004.
