Born November 17, 1944 in Rotterdam, his career took off when he helped found The Office for Metropolitan Architecture (OMA) in 1975. Koolhaas quickly became known for his different approach in a time where postmodern classicism was the prevalent design style. Scholars have a difficult time classifying his style, blending deconstructivism, structuralism, and modernism. Many find his work hard to understand, seemingly a jumbled assortment of unusual silhouettes, unexpected shapes, and hard edges. While his structures at first seem impractical, a closer look reveals an effective use of technology and space, completely reforming the way the world views functionality.
