Marshall Blutcher Gardner (November 30, 1854 - January 24, 1937) was a Canadian-born textiles manufacturer, specifically corsets and allied garments, and 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).

  "While we have not yet exhausted the resources of the outside of the globe, we can see in imagination the time not far distant — when the outside will be too thickly populated and too thoroughly drained of its resources. Thus the discovery of the new continents may be due to be made at a providential time. At all events, I think the prospects are sufficiently interesting to justify me in calling upon men of science of public spirit everywhere — throughout the United States as well as throughout the world — to take this matter up; to discuss it thoroughly and without prejudice; to get behind the idea and push it; to interest their friends in it; to look forward to, and to help forward any movement such as an American expedition or an international expedition, to verify and map out the discoveries here predicted through the means of reason and observation. The time is ripe for such a move. It should be made in a spirit of friendliness between the nations involved, and should be free from national jealousies and the desire of gaining undue advantages."
