From Kook Science
- Not to be confused with Thomas Mozette (d. 1926), a clairvoyant con-artisan who used the alias Francis Cook while active in California.
Francis Cook was the name of an individual profiled in a 1936 article by Whit Wellman for the Five Star Weekly news magazine, in which it reported he was a resident of San Francisco who had devised both death and life rays, among other electrical devices of similar character. Cook was also said to have been raised in Arabia and to have spent his youth traveling through Egypt and India, during which time he was initiated into many esoteric religious practices, including "a dozen" baptisms, and that these initiations were the cause of an "M" mark on his forehead indicating "Master."
