Giles Peppiatt studied at St. Andrews University in Scotland before joining Bonhams in 1989. In 1993 he trained as an auctioneer and conducted his first sale in that year. He qualified with the Royal Institute of Chartered Surveyors as a 'Chartered Arts & Antiques Surveyor' in 1997.
Giles established the 'The South African Sale' in 2007; a field in which Bonhams now leads the market. These sales now turn over a greater value of artwork than is sold in all of South Africa, and have established London as the centre for the South African Art market.
Continuing with his work with African art, Giles presented the first London sale of Contemporary African Art, 'Africa Now', in April 2009. This sale and exhibition was critically acclaimed and brought this hitherto unknown but vibrant market to the attention of many collectors and institutions. These auctions established Bonhams as the market leader in Contemporary African Art and also confirmed Bonhams credentials as the world leader in all matters relating to the art of Africa.
