Walter Carruthers Sellar (27 December 1898 – 11 June 1951) was a Scottish humourist who wrote for Punch. It was at Oriel College Oxford that he met his contemporary Yeatman, and struck up a lifelong friendship. He is best known for the 1930 book 1066 and All That, a tongue-in-cheek guide to “all the history you can remember,” which he wrote together with R. J. Yeatman.
Robert Julian Yeatman (15 July 1897 – 13 July 1968) was a British humorist. When asked to convert his BA from Oxford into an MA, Yeatman could not find the fee owing to debt, and hence he is recorded in 1066 and All That as “Failed M.A., etc. Oxon”.
Although the two produced brilliant work together, they were entirely different personalities: Sellar was somewhat shy and introverted, although he enjoyed acting. He wrote melancholy poetry in addition to dry humour.
