Coming to Princeton from Warren High School in Ohio, where he was a class officer, Frank became president of Elm Club and a member of the Inter-Club Committee. He rowed on the lightweight crew and was active in intramural sports and the Princeton Chapter of the American Institute of Architects. His senior-year roommates were Howie Boose, Dick Moore, and Lindsay Steen.

Following service as a lieutenant in the Navy, he studied at the University of Geneva, Switzerland, where he met and married his wife, Ingrid E. Glatz. Thereafter he studied at Columbia (B.Arch.) and Harvard, attaining a master’s degree there.

As an architect, Frank worked for many years in Europe, winning several design prizes in Munich, and then joined the American firm of McMillan, Griffis & Mileto, working in its office in Rome. Later, he became a partner with Brown Daltas and Associates, heading up offices in Rome, New York, Mexico, and Cambridge, Mass. The firm’s signature project was the King Khalid Military City in Saudi Arabia. Finally, he formed Elliott and Associates, designing numerous noteworthy buildings in the Boston area.

Frank is survived by his wife, Ingrid; children Karin and Mark; and three grandchildren.
