Send a message to the person who requested a photo of the grave monument of Frederick George Spray with the following comment:
Frederick George Spray was a civil engineer with expertise in gunpowder manufacture. It is likely that he was in Russia when the Crimean War was taking place (1853 to 1856). Possibly he was the ‘clever chemist’ (see London Daily News, 20 Oct 1855) responsible for the production of gunpowder from sodium nitrate. This was something very new at that time.I would appreciate it if you send me a copy of image number 544983 so that I can use it in the presentation at a talk on this subject that I shall be giving early next year.
