My name is Ulf Möller. I have been mapping in Munich and the Bavarian Pre-Alps (first under a pseudonym, now as user ulfm) since I discovered OSM in 2007.
I am a member of the OSMF's Licensing Working Group and was a member of the board in 2009/10.
Ulf Möller was killed in January 2012: https://blog.openstreetmap.org/2012/01/18/ulf-moller-1973-2012/?lang=de
