Verne, Jules
From the Earth to the Moon (1867)
From the Earth to the Moon 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.
Though written many years before manned space flights the story bears many similarities to the real-life Apollo program and considering the total lack of any data on the subject at the time, some of Verne's figures are surprisingly close to reality.
