Robert Duncan Tonningsen Dec. 18, 1930-Nov, 7, 2012 Resident of Redmond, WA Duncan was born and spent a large period of his life in Alameda. He graduated from Alameda High School, UC Berkeley, and UCSF School of Dentistry. After a brief stint in the Army as a dentist during the Korean War
, Duncan practiced dentistry in Alameda for more than 30 years before retiring to live near Seattle. He was loved and respected in both communities and renowned for his generosity. He was a member of the Alameda Elks, Rotary Club
, Encinal, Aeolian, Richmond Yacht Clubs, Claremont Country Club and served on the board of Alameda Federal Savings and Loan. An avid bridge player and competitive sailor, Duncan is recognized in many yacht clubs around the Bay, especially for his deft skippering of The Damn Yankee. He was a voracious reader, loved opera and film noir, and enjoyed golf, skiing, and duck hunting. He once built a wood boat from scratch, bought a Pacer thinking it was the car of the future, had a penchant for elaboration, and was known to enjoy a good meal and glass of wine. A fun-loving spirit, Duncan lived a full and productive life, had many friends, and will be sincerely missed. Duncan was preceded in death by his second wife Margaret Tonningsen and eldest son Eric Tonningsen. He is survived by his former wife Sally Chapman, his three children, Peter, Kirstin, and Duncan James, his four grandchildren Dylan, Seth, Clara, and Ellis. Per Duncan's wishes, no services will be held. In his memory, we are sure he would have appreciated you doing something to help a friend.
