In 1890 Yule graduated from UCL where he studied engineering. After two years as an engineer, and a year researching in physics, he was appointed by Karl Pearson to a demonstratorship at UCL. Yule’s first paper on statistics appeared in 1895. In 1911 he published Introduction to the Theory of Statistics which was the standard reference book on mathematical statistics for the next forty years (the fourteenth edition, written jointly with Sir Maurice Kendall, was published in 1950). In 1912 he moved to Cambridge U, where he spent most of the rest of his life, retiring in 1931 (when he learnt to fly and obtained his pilot’s licence). During his time at Cambridge he worked on the theory of time series, introducing the terms correlogram (see autocorrelation) and autoregressive models. He was elected FRS in 1921. He was President of the RSS in 1924, having been awarded its Guy Medal in Gold in 1911.
