V Pack, I am fascinated by your story and would love to hear more. I am an Oberdieck and Rudy was my grandfather. He died soon after I was born and I do not have many stories of his life. I do have a collection of Ursula`s drawings and sketches, but sadly, her stories passed away with her. My father was an artist for a time, but not an architect. I would be so interested in hearing and learning more from you. Is there a way for me to contact you off the site? Thank you so much for sharing.
