There was a space elevator on Mars in Kim Stanley Robinson s Red Mars trilogy. 

Clarke s most famous novel on a space elevator was The Fountains of Paradise. 

In his 195Os novel The Sands of Mars Clarke had Phobos ignited to help the colony there get extra light and warmth along with the native life forms.

Didn't Arthur C. Clarke put his first space elevator in Mars orbit?

We won't start with an Earth-GEO elevator, anyway. 
  
It makes much more sense to build rotating skyhooks o[erating in lunar orbit, starting with 
small payloads to and from the lunar surface -- 200-400 KG or so. Sample retrieval canister 
size. Single suited astronaut size. Well within available material strength.

We won't go after a space elevator anchor point until we need a space elevator. We won't grab an asteroid and park it on the off-chance that we'll decide someday to build one. Will we need a space elevator any time soon? I'm sorry, I just don't see it, as cool as it would be.
