Harold Baillie-Weaver (1861 – 18 March 1926) was an English barrister, Theosophist and animal welfare campaigner.

[4] Baillie-Weaver was a vegetarian for ethical and spiritual reasons, believing that meat eating was an outrage to the Fatherhood of God, thus morally indefensible.

In 1935, notable members of the organisation were Clare Annesley, Yvonne Arnaud, Robert H. Spurrier, Commander John Leonard Cather, J. Morewood Dowsett, Bertram Lloyd, H. V. Morton, Bindon Blood, D. Jeffrey Williams, Laurence Housman and Desmond Shaw.

[17] Baillie-Weaver was in ill health for a year before his death at the age of 65 on 18 March 1926 at his residence in Wimbledon.

His splendid personality influenced all who came within his ken, and all those who knew him felt inspired and uplifted in his presence".

[19] A "Protecting the Defenceless" bronze statue sculptured by Charles Leonard Hartwell in 1931 in memory of Baillie-Weaver and his wife is located in the gardens of St John's Lodge, London.
