Sir Stephen Gaselee KCMG CBE (9 November 1882 – 1943) was a British diplomat, writer, and librarian.
He wrote on "classical literature, medieval and modern Latin ... Coptic, hagiography and liturgiology, palaeography and bibliography, Spain, Portugal, Madeira, wine and food".
His friend Ronald Storrs characterised him during their undergraduate days as follows: Stephen Gaselee was already at the age of twenty what he never ceased to be, a Cambridge Personality; Gaselee, with almost as many friends as interests, a first-class classical scholar, a bibliophile, a bibliographer, a liturgiologist; Gaselee, who when playing tennis wore his hair in a net; who kept Siamese cats, fed with a revolting portion of cow’s lung preserved on a plate above his bookshelf; who had a fire every day in the year because England has a cold climate; who founded the Deipnosophists’ dining club, where the members, robed in purple dinner-jackets lined with lilac silk and preluding dashingly on Vodka, would launch forth into an uncharted ocean of good food and even better talk; Gaselee, who read, wrote and spoke Ancient Coptic (which the Copts themselves had not done for 300 years); Gaselee, nightly puffing his long churchwarden whilst he expatiated on Petronius, vestments, Shark’s Fin and cooking problems; a lay Prince of the Church, Ecclesiastic Militant and Gastronomer Royal.
A group of benefactors bought his personal collection of works relating to Petronius and the Satyricon from his heirs and gave it to Cambridge University Library.
He was appointed a Commander of the Order of the British Empire in the 1918 New Year Honours for his efforts during the First World War, when he worked in the Foreign Office Department of Information.
