Sir Sidney Colvin (18 June 1845 – 11 May 1927) was an English curator and literary and art critic, part of the illustrious Anglo-Indian Colvin family. He is primarily remembered for his friendship with Robert Louis Stevenson. A scholar of Trinity College, Cambridge, Colvin became a fellow of his college in 1868. In 1873 he was Slade Professor of Fine Art and was appointed in the next year to the directorship of the Fitzwilliam Museum. He wrote numerous articles on fine arts subjects (including Sandro Botticelli, Albrecht Dürer, Fine Arts, Leonardo da Vinci, and Michelangelo) for the ninth edition (1875–89) of the Encyclopædia Britannica. In 1878, 114 Old Master engravings, which Colvin had purchased for the museum from London art dealer A. W. Thibaudeau were stolen by a hansom cab driver. Although the driver was tracked down and charged, the engravings were never recovered and Colvin was required to cover their cost. Colvin paid the £1,537 10s to Thibaudeau from his own salary in installments for many years, having initially to borrow £400 from Robert Louis Stevenson; a debt which he was still repaying to his friend in 1884. In 1884 he moved to London on his appointment as keeper of prints and drawings in the British Museum. His chief publications are lives of Walter Savage Landor (1881) and Keats (1887), in the English Men of Letters series; editions of the letters of Keats (1887); A Florentine Picture-Chronicle (1898), and Early History of Engraving in England (1905). In the field both of art and of literature, Colvin's fine taste, wide knowledge, and high ideals made his authority and influence extend far beyond his published work Less
