Hume graduated in physics from
Birkbeck College. He was honorary secretary of the British Science Guild and edited the journal
Proceedings of the Physical Society (1919–1940). He served in the
Royal Engineers during
World War 1 and the
47th Divisional Signals (Territorial Army) during
World War 2. He has also been credited as the first to use the expression "animal welfare". Richard P. Haynes has suggested that "Hume should be credited as the father of the animal welfare movement". A review noted that "these subjects are dealt with objectively and clearly, lightly yet seriously, tactfully yet persistently, especially in the factual and historical aspects." The Charles Hume Memorial Fund was set up in his honour. ==Selected publications==
