Jan Joseph Kalas, an architect who split his time between Brooklyn and East Hampton for many years and continued to keep a sailboat here, died on Oct. 31 after being struck by a car in Long Beach on his way to work. He was 70.
Mr. Kalas practiced architecture for 40 years, 20 of them at the engineering firm Thornton Tomasetti, where he was a senior vice president. The firm said he was “known for his problem-solving ability and eye for detail.” Colleagues described him as quick-witted and full of energy.
