Arthur J. Sulley was a prominant London art dealer. At the beginning of his career, Sulley (d. 30 October 1930) was connected with the firm of Thomas McClean in the Haymarket; he then became a partner in the firm of Laurie and Company, of London and Glasgow. Subsequently Sulley began his own gallery on New Bond Street in partnership with Mr. Brown. In the years before his death, Sulley had conducted his business from a private house on Grosvenor Street. His important clients included P.A.B. and Joseph Widener. It was Mr. Sulley who conducted the negotiations for the transfer of Rembrandt's The Mill, now in the NGA collection, from Lord Landsdowne's collection. Sully's letters to Bernard and Mary Bereson, dating from 1910-1929, are at the Harvard University Center for Italian Renaissance Studies in Florence.
