Francis Prior Lacy was killed in France on August 18th, 1915, while entering at mine, through the explosion of a counter-mine of the Germans. He was a Captain in the Tunnelling Section of the Royal Engineers, and was 28 years of age.
He received his technical training at the Royal School of Mines and, after taking the Associateship in 1911, was awarded a £50 Scholarship by the Institution and was also selected for a post-graduate practical course at the mines of Messrs. Denny Bros. in Mexico, for the satisfactory completion of which he received the Institution certificate. He remained with Messrs. Denny Bros. until the autumn of 1914, when he returned to England and obtained a commission in the Cumberland and Westmorland Yeomanry, but afterwards he obtained a transfer to the Royal Engineers. He was awarded the Military Cross for conspicuous courage whilst engaged in tunnelling operations and was promoted to the rank of Captain.
Mr. Lacy was admitted to Studentship of the Institution in 1909.
