David passed away early in his 100th year on earth, the evening of Sunday, May 28, 2017.

David was born in Sarajevo, Yugoslavia (now Bosnia Herzegovina) on May 13, 1918, prior to the conclusion of World War I. He was a brilliant student and received a degree in aeronautical engineering from the University of Belgrade, Yugoslavia and a second degree in mechanical engineering from the University of Graz, Austria.

After World War II, he and his wife Maria and two children emigrated from Vienna, Austria to Chicago, where he worked in research at the Armour Research Foundation of the Illinois Institute of Technology at the University of Chicago. The family, including two daughters born in Chicago, then moved to Seattle where David was employed at the Boeing Company as an aeronautical engineer. At Boeing he played an important role in a number of significant projects such as the Saturn Rocket.

David and Maria have lived on Mercer Island for almost 60 years and were active in a number of organizations with an educational focus. All four daughters and three grandchildren graduated from Mercer Island High School.

David was a renaissance man, having learned seven languages including Latin and Greek, and had an interest in many subjects besides scientific inquiry. He loved classical music, his garden especially the roses and rhododendrons, his travels and photography. A very congenial man, he was always ready to engage in conversation, be it philosophical, political or cultural, and was loved and respected by all he met.

He is survived by his wife Maria, his daughters Burgi (Mercer Island), ​L​lse and Sylvia (California); grandchildren Luis, Marc and Renee (Seattle) Doug, Peter, Kristen, Megen and Cameron (California and Utah) and twenty three great grandchildren. He was preceded in death by his daughter Marina.
