It was 2001. The last Christmas card I got from him was 2000. Can't remember for sure who let me know that he had passed, maybe Tom Nakosone (sp) who had been one of the IAAM'ers that had helped him liquidate some of his collection and ship the rest to Germany. Lost track of
him also and Steve Amos who was one of Olaf's best friends. Not a lot of us left from that group.
