Heymans, Gerardus (1857–1930)
Psychologist, philosopher, and pioneer of parapsychology
in the Netherlands. Heymans established a laboratory for reHettinger,

search in 1892 and led in the spread of experimental parapsychology
in Holland in the years immediately after World War
I. He was one of the founders of the Studievereniging voor
Psychical Research (SPR), inaugurated on April 1, 1920, and
served as its first president. The Dutch SPR served as a meeting
ground for scientists, scholars, Spiritualists, and Theosophists.
Heymans followed the philosophy of psychic monism, according
to which the universe consists of one stuff, consciousness
of which each individual partakes. Having discovered a
psychically gifted student, Heymans conducted telepathy experiments
at the University of Groningen, tests widely cited for
both design and positive results.
