Sir Oliver Lodge, FRS (June 12, 1851 – August 22, 1940) was a British physicist involved in the development of key patents in wireless telegraphy. He began to study psychic phenomena in the late 1880s. He was a member of The Ghost Club, and president of the Society for Psychical Research from 1901 to 1903. Lodge's book Raymond or Life and Death (1916) documented the communication between him and his wife and their son Raymond through the medium Gladys Osborne Leonard. Raymond was killed in World War I.
