Dr David Lambert of the Warwick University History Department gave a public talk on Tuesday 5 May at gallery@oxo on London's Southbank as part of the 'Jamaica Hidden Histories' exhibition. He spoke about the anthropologist and geographer, Harry Johnston (1857-1926), whose early 20th-century photographs of the Caribbean form part of the exhibition. The originals are held at the Royal Geographical Society (with the Institute of Geographers) in South Kensington. 'Jamaica Hidden Histories' runs until 17 May, before it moves to The Drum arts centre in Birmingham from 25 June.
