Brian Brason, a regular contributor to Swift Annual, writing anonymously for volumes 3 through 8 (1956-61). Unfortunately, I've no clue as to what he wrote. Brason was possibly the author of a single booklet, The Story of Port Sunlight (Port Sunlight, Lever Brothers, 1953), a heavily illustrated history of Lever Brothers/Unilever's research and development department at Port Sunlight, on the Wirral between Chester and Liverpool.
The only Brian Brason I've been able to trace in geneological records (although I've only done a brief search) is Brian Luke Brason (b. 18 August 1920, d. 31 December 1983, aged 63, in Aylesbury, Bucks.). Brian Luke Brason lived in North Harrow in the 1950s and 1960s. The surname Brason is rather uncommon, so there's a good chance the Swift Annual author and Brian Luke Brason are one and the same.
