The questions floated around in my head for awhile, but it wasn't until last Sunday that I decided to act on them. Inspired by Houdini, I made up a basic pass/fail test that I could apply a few times to see if someone was actually in tune with all the truths in the universe: If I made up a dead sister and asked a bunch of psychics to connect with her, how many wouldn't be able to tell I was full of shit?
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).
