Leonard Simpson was born in Darwen Lancashire on 28th April 1886. He was the youngest son of Henry and Margaret Anne Simpson. His father was a Director of a wallpaper manufacturing company. He was educated at University School, Southport and Kings College London. He became a clerk, probably in his father’s company, and later moved on to be Office Manager. On 28th December 1911 he married Margaret Mary Hughes in Paddington, London giving his occupation as “gentleman”. Margaret had previously lived with her family in Shrublands Road, Berkhamsted.
Leonard enlisted in December 1914 and joined the Inns of Court for officer training. His application letter mentioned that he could speak German, Romanian and Polish and that he had considerable experience in mining engineering in Austria and Romania. On 12th January 1915 he was appointed as 2nd Lieutenant with the Royal West Surrey Regiment. He never saw active service because he contracted influenza and bronchitis in early April 1915. This led to further gastric and breathing problems; he was discharged on 9 February 1916 and was issued with a Silver Badge (No. 3135) on 11th November 1916. His address was 15 Greenway, Berkhamsted.
Second Lieutenant Leonard Simpson died on 6th April 1920, leaving his wife and one daughter, Marion who was born in late 1915. When Margaret died in 1955, her address was 11 Greenway.
