This man gets a seat (4)

I believe the answer is:

otto

I'm a little stuck... Click here to teach me more about this clue!

'this man' is the definition.
(I have seen 'A man' mean 'otto' so perhaps 'man' could also mean 'otto')

I can't explain the remainder of the clue.

Can you help me to learn more?

(Other definitions for otto that I've seen before include "German man's name" , "Something oily" , "Palindromic German name like Bismark's" , "- Preminger, Austrian-born US film producer" , "Swiss perhaps" .)

I've seen this clue in The Globe and Mail.
