JOHNSON-Philip. In a statement today (27), Thomas J. Pritzker, president of The Hyatt Foundation, expressed the sadness of the jurors of the Pritzker Architecture Prize, as well as the Pritzker family, over the death of Philip Johnson. ``Philip Johnson was the first Pritzker Architecture Prize Laureate in 1979,'' said Pritzker, ``and the jury praised him for his work as a critic and historian who not only championed the cause of modern architecture, but went on to design some of the 20th Century's great buildings. At that time, he was being honored for 50 years of imaginative and vital structures. His career continued undiminished for another quarter of a century.'' When Mr. Johnson accepted the Pritzker Prize, he thanked The Hyatt Foundation ``in the name of all the architects of the world.'' He called the moment ``a symbol of impending change...'' marking the end of second class status of the visual arts and architecture. Pritzker added, ``We are grateful that as the first Pritzker Laureate, Philip became an inspiration for the field of architecture. We are also grateful to have had his guidance and vision as a member of the jury from 1980 through 1985.''
