Manly P. Hall (1901-1990) founded the Philosophical Research Society, an organization dedicated to the dissemination of useful knowledge in a variety of philosophical fields. He is best known for his 1928 classic, The Secret Teachings of All Ages.

Arthur Machen (Arthur Llewelyn Jones), a Welsh author of supernatural, fantasy, and horror fiction, was born on March 3, 1863. He grew up in Caerleon, Monmouthshire, and attended boarding school at Hereford Cathedral School.

He moved to London in 1881 and worked as a journalist, children's tutor, and publisher's clerk, finding time to write at night. By 1894, Machen had his first major success.

The Great God Pan was published by John Lane, and despite widespread criticism for its sexual and horrific content, it sold well and went into a second edition.

In the 1920s Machen's work became immensely popular in the United States, but Machen experienced increasing poverty; he was saved in 1931 by receiving a Civil List pension from the British government. Arthur Machen died on March 30, 1947.
