A new exhibition at the Met—the first major museum retrospective on Paul Rudolph—reminds us of the value of the artist’s hand in architectural drawings. Paul Rudolph (1917-1997) is what you might call an acquired taste. While the modernist architect dabbled in elegant international style beach houses, swanky townhouses for the glitterati, and dizzying conceptual megastructures, he’s best known for his mammoth brutalist buildings, many of which have been on the losing end of high-profile historic preservation debates.
