Louis Kahn
Louis Isadore Kahn was born on March 5 [O.S. February 20] 1901. He was an Estonian-born American architect based in Philadelphia. Kahn created a style that was monumental and monolithic; his heavy buildings for the most part do not hide their weight, their materials, or the way they are assembled. His concrete designs from the 1950s were studied at Tokyo University's Kenzo Tange Laboratory, influencing a generation of Japanese architects and stimulating the metabolism movement in the 1960s.
