In his novels 'From the Earth to the Moon', and 'Around the Moon', Jules Verne writes about a set of rockets fitted to the spacecraft he imagined, that were intended to be fired in order to slow down the fall to the moon's surface. Later in the adventure, they are indeed fired, but in order to change the trajectory...
Verne wrote all that in the 1860's. Was he the first to propose the retro-rocket?
