H. G. Wells 
The First Men in the Moon 

H. G. Wells‘ 1901 science fiction novel, ‚The First Men in the Moon‘, is the story of an impoverished businessman, Mr. Bedford, who retreats to the countryside for some rest from the weary of modern life and to try his hand at authoring a play. While there he meets an eccentric scientist, Dr. Cavor, who is developing a new material, ‚cavorite‘, which is designed to shield off gravity. When it is discovered that the material works and can be practically fashioned into a spaceship, the two undertake a mission to the moon. There they discover that the moon is inhabited by a sinister alien civilization, whom the call ‚the Selenites‘. Fashioned as a criticism against imperialism, ‚The First Men in the Moon‘ draws upon a theme common to Wells‘ work, that of the impact of technology on society and the challenges that humans face in the modern world.
