Mental Radio

A strange and sincere artifact of early-twentieth-century science: Upton Sinclair, best known for The Jungle, spent years documenting informal telepathy experiments with his wife, Mary Craig Sinclair, in which she attempted to reproduce drawings made by Sinclair and others in a separate room. Published in 1930 with a preface by Albert Einstein and an introduction by psychologist William McDougall, Mental Radio is less a scientific proof than a fascinating window into the era's genuine fascination with the unexplained, recorded in exhaustive, good-faith detail by one of America's most committed muckrakers.
