John Hejduk (1929–2000) was an American architect, educator, and theorist known for his poetic, experimental approach to architecture. A longtime dean at Cooper Union, he profoundly influenced architectural education. Hejduk’s work, such as the Wall House series and the Masques projects, explored narrative, symbolism, and spatial abstraction. He prioritized conceptual and artistic expression over conventional function, often blurring the line between architecture and sculpture. His writings and drawings continue to inspire architects, shaping discourse on architecture’s role beyond mere utility. Though few of his designs were built, his intellectual contributions cemented his status as a visionary in the field.
