(1897–1967), associated with the BBC Children's Hour from 1933 to 1950. Having been severely injured in World War I, McCulloch joined the BBC as an announcer in 1926. His aim when appointed London Children's Hour organizer in 1933 was to develop a somewhat homespun program along more professional lines, without ever losing the personal touch. In its early phase with “uncles” and “aunties” he was Uncle Mac; he later abolished these titles, and used his only in his children's publications. McCulloch rapidly became a national figure, and was particularly associated with the part of Larry the Lamb in S. G.Hulme Beaman’s Toytown plays, possibly the program's best- loved series. In 1938, McCulloch was made Children's Hour director, an appointment coinciding with the loss of a leg in a traffic accident. After retirement he worked as children's editor for the News Chronicle. He edited several collections of stories and also wrote his own, the most popular being Cornish Mystery (1950).
