William Crookes (1832 – 1919)

British physicist and chemist, member of the Royal Society, William Crookes was an experimenter of ectoplasmic phenomena and materializations. Thanks to a young medium named Florence Cook, he obtained numerous times the complete materialization of the phantom of the spirit of Katie King.

“Having assured myself of the reality of the spirit phenomena, it would be moral cowardice to refuse them my testimony: I am not say that this is possible, I say it is!”
