Fitzsimons, Frederick William (1875– )
South African scientist and Spiritualist. Fitzsimons was an
expert on snakes and was curator of the Natal Society Museum,
Pietermaritzburg, Natal. His interest in Spiritualism led him
to investigate psychic photographer William Hope and to sit
with Etta Wriedt while in London in 1920. He later published
one book, Opening the Psychic Door (1933).
