Stefan Kurylowicz, 62, a Polish architect who helped modernize Warsaw in the two decades after the collapse of communism, was among four Poles killed Monday when their two small planes crashed in Spain, an associate said Tuesday.

Mr. Kurylowicz (pronounced Kur-eh-WOH-vich) was "a Renaissance man," the Polish news agency PAP said. Born in Warsaw in 1949, he helped shape the capital as it evolved from a city dominated by drab communist-era architecture to a modern city dotted with tall glass and steel structures - some of the architect's creation.

Mr. Kurylowicz and his associates designed residential, commercial, and industrial buildings; some won awards. Last year he was among a group of outstanding architects chosen worldwide to advise the United Nations on a renovation of its New York headquarters. - AP
