Late professor's nephew as knight errant (7,7)

Ross

I believe the answer is:

stephen hawking

'late professor's' is the definition.
(physicist Professor Stephen Hawking)

'nephew as knight errant' is the wordplay.
'errant' indicates an anagram (errant can mean travelling or straying).
'nephew'+'as'+'knight'='nephewasknight'
'nephewasknight' is an anagram of 'STEPHEN HAWKING'.

I've seen this clue in The Guardian.
