From the Earth to the Moon (1865) is a humorous science fantasy novel by Jules Verne and is one of the earliest entries in that genre. It tells the story of a Frenchman and two well-to-do members of a post-American Civil War gun club who build an enormous sky-facing columbiad and launch themselves in a projectile/spaceship from it to a Moon landing.The story is also notable in that Verne attempted to do some rough calculations as to the requirements for the cannon and, considering the total lack of any data on the subject at the time, some of his figures are surprisingly close to reality.
