The History of Spiritualism, Volume I

The research into the phenomena of Spiritualism by Sir William Crookes-or Professor Crookes, as he then was-during the years from 1870 to 1874 is one of the outstanding incidents in the history of the movement. It is notable on account of the high scientific standing of the inquirer, the stern and yet just spirit in which the inquiry was conducted, the extraordinary results, and the uncompromising declaration of faith which followed them. It has been a favourite device of the opponents of the movement to attribute some physical weakness or growing senility to each fresh witness to psychic truth, but none can deny that these researches were carried out by a man at the very zenith of his mental development, and that the famous career which followed was a sufficient proof of his intellectual stability. It is to be remarked that the result was to prove the integrity not only of the medium Florence Cook with whom the more sensational results were obtained, but also that of D. D. Home and of Miss Kate Fox, who were also severely tested.

Sir William Crookes, who was born in 1832 and died in 1919, was pre-eminent in the world of science.
