Sir Alan Charles Laurence Whistler CBE (21 January 1912 – 19 December 2000) was a British glass engraver and poet.

Charles Slegg Ward, vicar of Wootton St Lawrence in Hampshire, whose wife, Jessy, was granddaughter of the goldsmith and silversmith Paul Storr.

Verse works of his included 'The Emperor Heart' ; 'Four Walls'; 'Armed October and other Poems'; and 'In Time of Suspense', in 1940, published by William Heinemann.

[3] He engraved on goblets and bowls blown to his own designs, and (increasingly, as he became more celebrated) on large-scale panels and windows for churches and private houses.

Other engravings of his can be found, for example, in Salisbury, where his family lived during part of his childhood, including a pair of memorial panels with quotations by T. S. Eliot, and the Rex Prism in the Morning Chapel, both in Salisbury Cathedral; at the Ashmolean Museum; at Balliol College, Oxford where he was an undergraduate, and St Hugh's College, Oxford, where he also designed the Swan Gates leading from the college grounds onto Canterbury Road;[4] at Stowe House in Stowe, Buckinghamshire; at the village church of St Nicholas at Moreton, Dorset, where every window was engraved by him over about 30 years; and in the Corning Museum of Glass (USA).
