Allan Frederick Sierp (17 May 1905 – 28 September 1982) was a South Australian artist, author of a series of technical drawing books used in Australian schools.
He was generally known as "Allan F.
Sierp", perhaps to distinguish him from the Adelaide violinist Allan Sierp L.T.C.L.
(Licentiate of Trinity College London), who was active in Adelaide 1920–1940.
