Ele era o mais velho de sete filhos de James Fleming (falecido em 1879), um ministro congregacional, e sua esposa Mary Ann, em Lancaster, Lancashire, e batizado em 11 de fevereiro de 1850. Um cristão devoto, ele uma vez pregou em St Martin-in-the-Fields em Londres em evidência para a ressurreição.
Em 1932, ele e Douglas Dewar e Bernard Acworth ajudaram a estabelecer o Movimento de Protesto da Evolução (uma organização criacionista britânica que reivindica o título de "o movimento criacionista mais antigo do mundo"). Fleming legou grande parte de sua propriedade para instituições de caridade cristãs, especialmente para os pobres. Ele era um fotógrafo notável, pintava aquarelas e gostava de escalar os Alpes.[1][2]
