Jean Pierre Allaire was counselling a 13-year old Trois Rivieres girl who reported seeing people that others could not. He told the girl she should go to the medium to find out whether she has a psychic gift. He also told her not to tell her psychiatrist about what she was seeing and hearing because that might lead to an increase in the anti-psychotic medications she was taking, which were making her sleepy.
Some scientists of the period who investigated spiritualism also became converts. They included chemist Robert Hare, physicist William Crookes (1832–1919) and evolutionary biologist Alfred Russel Wallace (1823–1913). Nobel laureate Pierre Curie took a very serious scientific interest in the work of medium Eusapia Palladino. Other prominent adherents included journalist and pacifist William T. Stead (1849–1912) and physician and author Arthur Conan Doyle (1859–1930).
