German banker seen in Heidelberg (4)

I believe the answer is:

elbe

'german banker' is the definition.
(I've seen this before)

'in heidelberg' is the wordplay.
'in' indicates a hidden word.
'ELBE' is hidden in the letters of 'heidelberg'.

'seen' is the link.

(Other definitions for elbe that I've seen before include "A major German river" , "Dresden and Hamburg's river" , "German banker" , "Flower" , "European river" .)

I've seen this clue in The Sun.
