Now the answer to who was the mystery person in the photo with me in my post on 10/13/07 "Who is the masked person with me?". Jimmy Bergmark in the comments wins as it was indeed the legendary Mr. John Walker the founder of Autodesk and now the owner of popular website http://www.fourmilab.ch/.
It was an absolute pleasure to meet the founder of Autodesk this summer while I was traveling in Switzerland. He was so very friendly and has a memory like no other person I have met before. It was a CAD Geeks dream come true. I made sure to tell John how much of an impact he made on many of us who started on AutoCAD. I will reveal more details on this exciting visit in the future in this 25th anniversary of Autodesk.
