Anthony Frederick Augustus Sandys (born Antonio Frederic Augustus Sands) (1 May 1829 – 25 June 1904), but usually known as Frederick Sandys, was an English "Pre-Raphaelite" painter, illustrator and draughtsman, of the Victorian era.
He married Georgiana Creed, but this marriage only lasted three years, although they never divorced. He had a long affair with the Romany woman Keomi Gray, who sat as a model both for him and Dante Gabriel Rossetti, and perhaps also for Simeon Solomon.He and Gray had at least two sons.
In 1862 Sandys met actress Mary Emma Jones, known as Miss Clive, when she modeled for The Magdalen, now owned by the Norwich Castle Museum. A relationship developed between the two, he became devoted to her, taking her as his common-law wife for the rest of his life. She gave birth to a large number of children, 10 of whom were raised under the name of Neville and survived after Sandys' death. His work Proud Maisie made in 1867, was inspired by Mary, so much so that he made at least 11 versions by 1904.
He died in the Kensington area of London in 1904.
