Boole - Ancestors & Descendants


 Leo Boole  1885 - 1935

Leo Boole was a great-nephew of George Boole (1815-1864), the mathematician who invented Boolean logic as used in computers today. Leo resembled George in looks and intellect - he was an Oxford scholar who taught classics and languages.

He was unfortunate enough to be visiting a German cousin, Enid Marschall, in Cologne when war broke out in 1914. Leo was imprisoned in Ruhleben camp, where he played a prominent part in the running of the Camp School, which had about a hundred teachers and more than a thousand pupils. Leo was in charge of the French department.

The biggest problem was lack of places to hold the classes. These were held outside in warm weather, but at other times had to squeeze into any available loft or box (small rooms into which the barrack huts were divided). Classes were aimed at the British Board of Education examinations, and the Board sent to Ruhleben the syllabuses and several hundred books for a camp library.

Leo and Enid kept in touch throughout the war and she visited him when she could get permission. Ironically, in the later years of the war, the Germans were suffering such deprivation that Leo was giving food (which he had received from his relatives in England) to Enid. In return, Enid knitted warm clothes for Leo. On release in 1918 they married and moved to England. He taught in Sedbergh, Belper, Folkestone and London, but suffered increasingly poor health, and died in 1935 aged 50, when their only daughter Rose was 16. Enid lived until 1959
