Architect Jan Kaplicky. Jan Kaplicky, the dour but visionary Czech architect, died January 14 in Prague of a heart attack, within hours of the birth of his daughter. He was 71 and had been dividing his time between London and the Czech Republic, where he had several major commissions. After emigrating to England in 1968, Kaplicky worked with some of Europe’s best architects, including Denys Lasdun, Norman Foster, Richard Rogers, and Renzo Piano, the last two on the breakthrough Centre Pompidou in the mid-70s. He spent several years in Foster’s office before founding his own firm, Future Systems, in 1979.
