I am engineer and specialized in nuclear power plants safety. My main hobby is the collection of classic stamps, especially from the "Deutsches Reich" and the KK Austria-Hungary monarchy, with emphasis on the origin of the cancellations. I have developped databases for this purpose. 13 May 2012 - 20 Oct 2013
My grandfather was a landscape painter, and this reflects in the way I compose pictures.
I am autopatrolled since 1 November 2012.
