to William (a saddler) and Alice (née Hall). His parents were staunch and active Wesleyans who had eight children, of whom William was the eldest. In 1878 he entered the Central Foundation School, in London, where his ability to learn rapidly gave him leisure at the age of twelve to carry out simple chemical experiments in his bedroom. While at school he also developed great skill as a photographer—many of his early photographs were in perfect condition fifty years later. From there he moved to the Finsbury Technical College, where he learned much from H E Armstrong; the two later became close friends. Pope studied
