Rosemary Isabel Brown (nee Dickeson, 27 July 1916 – 16 November 2001) was an English composer, pianist and spirit medium who claimed that dead composers dictated new musical works to her. She created a small media sensation in the 1970s by presenting works purportedly dictated to her by Claude Debussy, Edvard Grieg, Franz Liszt, Franz Schubert, Frédéric Chopin, Igor Stravinsky, Johann Sebastian Bach, Johannes Brahms, Ludwig van Beethoven, Robert Schumann and Sergei Rachmaninoff.
Brown claimed that each composer had his own way of dictating to her: Liszt controlled her hands for a few bars at a time, and then she wrote down the notes; Chopin told her the notes and pushed her hands on to the right keys; Schubert tried to sing his compositions; and Beethoven and Bach simply dictated the notes. She claimed the composers spoke to her in English.

Mysterious rapping, eerie music, otherworldly voices — witnesses ascribed these strange phenomena and others to the historic séances of Margery “Mina” Crandon, one of America’s most celebrated spiritualist mediums. Read more here.

With Helena Petrovna Blavatsky and others he founded the Theosophical Society in 1875 and became its president. In 1878 he and Blavatsky visited India. The two settled there in 1879 and in 1882 established the permanent headquarters of the Theosophical Society of Adyar, Madras. Olcott was born on August 2, 1832 and died on February 17, 1907.

Charles Hoy Fort (August 6, 1874 – May 3, 1932) was an American writer and researcher who specialized in anomalous phenomena. The terms Fortean and Forteana are sometimes used to characterize various such phenomena. Fort’s books sold well and are still in print. His work continues to inspire admirers, who refer to themselves as “Forteans,” and has influenced some aspects of science fiction.
Fort’s collections of scientific anomalies, including The Book of the Damned (1919), influenced numerous science fiction writers with their skepticism and as sources of ideas. “Fortean” phenomena are events which seem to challenge the boundaries of accepted scientific knowledge, and the Fortean Times (founded as The News in 1973 and renamed in 1976) investigates such phenomena.

Andrew Jackson Davis (August 11, 1826 – January 13, 1910), known as the “Poughkeepsie Seer,” was an early healing medium and spiritualist. As a young man, he developed the ability to go into magnetic trance on his own, and in that state, he was able to diagnose disease. In the late 1840s, he claimed he met the spirit of the ancient Greek physician, Galen, who gave him a magic staff that he believed he could use for healing.

Helena Petrovna Blavatsky, often known as Madame Blavatsky; was a Russian occultist, philosopher, and author who co-founded the Theosophical Society in 1875.

Sir Oliver Joseph Lodge, FRS (12 June 1851 – 22 August 1940) was a British physicist and writer involved in the development of, and holder of key patents for, radio. He identified electromagnetic radiation independent of Hertz‘s proof and at his 1894 Royal Institution lectures (“The Work of Hertz and Some of His Successors“), Lodge demonstrated an early radio wave detector he named the “coherer“. In 1898 he was awarded the “syntonic” (or tuning) patent by the United States Patent Office. Lodge was Principal of the University of Birmingham from 1900 to 1920.
Lodge was also noted for his Spiritualist beliefs and research into life after death, a topic on which he wrote many books, including the best-selling Raymond; or, Life and Death (1916), describing what he believed to be detailed messages through a medium from his deceased adult son who was killed in World War I.
