Marshall Blutcher Gardner (November 30, 1854 - January 24, 1937) was a Canadian-born author of a Hollow Earth theory that posits there is a sun at the centre of our planet's interior, and that the other planetary bodies in our solar system are constituted likewise (based on his viewing of photographs of Mars).
