James Dickson, one of the founders of the RHS, and an expert in mosses, is buried in the churchyard at Sanderstead - see photo below. His main residence was at Covent Garden, but he bought a house in Croydon in the 1790s. He studied the bryophytes in the locality, including in Selsdon Wood. He chose to be buried at All Saints because of his love of the plants in the area. Many of his papers are held in the libraries of the RHS and Natural History Museum and the Croydon Museum has a leaflet about him written by the RHS. His works include a collection of mosses and hepatics, purchased by the Natural History Museum in 1876 and a number of books, also available from the Natural History Museum including: 103 original coloured drawings to illustrate Fasc.
