H. Stanley (Herbert Stanley) Redgrove

Born in 1887, Herbert Stanley Redgrove wrote under the name H. Stanley Redgrove and built a body of work that ranged from chemistry to occult and philosophical subjects. Sources connected with his books identify him as a B.Sc. (London) and F.C.S., and his publications show an unusual mix of scientific training and fascination with older traditions of thought.

He is best known for Alchemy: Ancient and Modern, along with books such as Bygone Beliefs, A Mathematical Theory of Spirit, Matter, Spirit and the Cosmos, and Joseph Glanvill and Psychical Research in the Seventeenth Century. His work often tried to place alchemy, mysticism, and psychical inquiry in conversation with modern science rather than treating them as simple curiosities.

Redgrove died in 1943. He remains an interesting figure for readers who enjoy early 20th-century attempts to bridge laboratory science, intellectual history, and the more speculative side of human belief.
