[Retros] Wolfgang Dittmann

[Thomas Brand]

I just noticed that in the mailing list there is no information that Wolfgang 
Dittmann, the Grand Old Man of retrograde analysis, the author of "Der Blick 
zurück" passed away at February 05, 2014. You may find an obituary here:

The Dittmann-80 tourney on logical retractors will now be continued as 
Dittmann Memorial; new closing date is June 14, 2014. This tourney will be 
judged by me. See e.g. here:
