<...but he won the brilliancy prize at Frankfurt 1887 for his game with Isidor Gunsberg.>
I think this statement is wrong.
Although his game with Gunsberg may have been brilliant, I don't think it won the Brilliancy Prize. Does anybody have a ref that it did?
<whiteshark> posted a link to a German writeup on Harmonist, which does mention the game, but it only offers this:
<One of his finest games was brought on the occasion of its centenary the chess friends in memory. It was played in 1887 in Frankfurt Master Tournament.>
The original link is stale, here's an archived version:

The game which did win the Brilliancy Prize did indeed involve Harmonist, but on the losing side of the board:
See Reinfeld's <Great Brilliancy Prize Games of the Chess Masters>, p17
Also, several mentions in BCM, e.g. v25 (1905) p57-8:
where it says:
<The Deutsche Schachzeitung, from which the notes to this game are taken, remarks: "For this game, which the 'Chess Monthly' calls the pearl of the tourney, Herr Schiffers received the special brilliancy prize of 100 marks, given by Mr. Lewis, of London.>
Batgirl mentions the Schiffers--Harmonist game as well, citing an earlier BCM ref which got the tournaments confused:
