Sylvia Gosse was the daughter of Sir Edmund Gosse an English poet, author and critic. Born into an artistic family with Sir Lawrence Alma-Tadema was her uncle by marriage. Gosse received her training first at the St. John Wood Art School and then at the Royal Academy of Art (1906-09).
in 1908, the artist Walker Sickert was impressed by her talent and decided that she should learn etching. She enrolled in Sickert’s evening classes, first as the Westminster School of Art and then at a private art school he founded in the Hampstead Road. Gosse eventually took over responsibility for running the school, which became known as Rowlandson House (alternatively the Sickert and Gosse School of Painting and Etching).
Her works are represented in the national collection at the Tate, Ashmolean, National Portrait Gallery and the Ingram Collection of Modern British Art.
