Scientist's obit chimes with organisation (10)

I believe the answer is:

biochemist

'scientist's' is the definition.
(biochemist is a kind of scientist)

'obit chimes with organisation' is the wordplay.
'with organisation' indicates an anagram.
'obit'+'chimes'='obitchimes'
'obitchimes' is an anagram of 'BIOCHEMIST'.

(Another definition for biochemist that I've seen is " Scientist".)

I've seen this clue in The Telegraph.
