Gwenn was born inWandsworth, London to John and Catherine (née Oliver) Kellaway.[2] His brother was the actorArthur Chesney, and his cousin was the actorCecil Kellaway. Gwenn was educated atSt. Olave's School and later atKing's College London.[1] He began his acting career in the theatre in 1895, and learned his craft as a member ofWillie Edouin's company, playing brash comic roles.[1] In 1901 he marriedMinnie Terry, niece of DameEllen Terry. In the same year, he went toAustralia and acted there for three years with theJ. C. Williamson company.[1] His wife accompanied him, and when Gwenn was in a production ofBen Hur that was a disastrous failure, she restored the couple's fortunes by accepting an engagement from Williamson.[3] Later, the couple appeared on stage together in London in a farce calledWhat the Butler Saw in 1905[4] and, in 1911, whenIrene Vanbrugh made her debut in variety, she chose Terry and Gwenn to join her in a short play specially written byJ. M. Barrie.[5]
When he returned to London, Gwenn appeared not in low comedy but in whatThe Times called "a notably intellectual and even sophisticated setting" at theCourt Theatre under the management ofJ. E. Vedrenne andHarley Granville-Barker.[1] There, in 1905 to 1907, in the words ofThe Times, "he was invaluable in smaller parts [giving] every part he played its full worth", including Straker, the proletarian chauffeur to John Tanner inBernard Shaw'sMan and Superman, and Drinkwater, thecockney gangster inCaptain Brassbound's Conversion.[1] He also appeared in plays by Granville-Barker andJohn Galsworthy, inElizabeth Robins's suffragette dramaVotes for Women[6] and in works by other contemporaries. In Barrie'sWhat Every Woman Knows (1908) in the role of the over-enthusiastic James Wylie he impressed the producerCharles Frohman, who engaged him for his repertory company at theDuke of York's Theatre.[1] In 1912, Gwenn went into management in partnership withHilda Trevelyan.[1] His career was interrupted by his military service during theFirst World War, serving as an officer in theBritish Army.[1] During the war, Gwenn's marriage broke up and was dissolved. His ex-wife remarried but remained on affectionate terms with him.[7]
After peace returned, Gwenn's leading roles in theWest End during the 1920s included Old Bill inBruce Bairnsfather'sOld Bill, M.P. (1922); Christian Veit inLilac Time (1922–23); the title role inA. A. Milne'sThe Great Broxoff (1923); Leo Swinburne inGood Luck bySeymour Hicks andIan Hay (1923); and Hippolyte Gallipot inLehár'sFrasquita (1925).[8] Looking back at Gwenn's career,The Times considered, "Out of scores of other parts which he played in England and in America, the best remembered are probably Hornblower in Galsworthy'sThe Skin Game, the Viennese paterfamilias inLilac Time and Samuel Pepys inFagan'sAnd So to Bed in 1926."[1]
Gwenn remained a British subject all his life. When he first moved to Hollywood, he lived at theBeverly Wilshire Hotel inBeverly Hills. His home in London had been reduced to rubble during the bombings by the GermanLuftwaffe in theSecond World War. Only the fireplace survived. What Gwenn regretted most was the loss of the memorabilia he had collected of the actorHenry Irving. Eventually, Gwenn bought a house at 617 North Bedford Drive in Beverly Hills, which he later shared with the former Olympic athleteRodney Soher.[12] At the age of 78 he travelled from his home in California for a reunion with his ex-wife in London.[7] He told a reporter, "I never married again because I was very happy with my wife. I simply stayed faithful to the memory of that happiness."[7]
