Inventor brings no side back (6)
I believe the answer is:
edison
'inventor' is the definition.
(I know that Edison is a inventor)
'no side back' is the wordplay.
'back' says the letters should be written in reverse.
'no'+'side'='noside'
'noside' backwards is 'EDISON'.
'brings' is the link.
(Other definitions for edison that I've seen before include "Prolific inventor" , "He came up with microphone" , "US scientist/inventor" , "Onside with great American inventor" , "No side to this american inventor" .)
