William Crookes' long life was one of unbroken scientific and business activity, culminating in his appointment as President of the Royal Society in 1913. Throughout his career he was an important science journalist, the discoverer of thallium, the inventor of the radiometer, investigator of cathode rays and the vacuum, a spectroscopist of significance in rare earth chemistry, and a spokesman for a chemical solution to the problems with the world's food supplies. He was also, and perhaps most controversially, an occultist who played a significant role in spiritualism in the 1870s, and was involved with D.D. Home (Browning's Mr Sludge) and other notable mediums of the day.

This book gives an incredible insight into a intersection of science and spiritualism of the early 20th century.
