Popular architectural figure Rem Koolhaas has a large following due to his unconventional and sometimes provocative buildings. In 1975, Koolhaas, his wife Madelon Vriesendorp, and Elia and Zoe Zenghelis opened OMA, a collective “hothouse research lab,” as described by Icon. In addition to architecture, Koolhaas is also an author (S, M, L, XL and Content), a theorist, an urban planner, a cultural researcher, and a professor at Harvard. Among his numerous projects, he has designed the Seattle Central Library, the Netherlands Embassy in Berlin, and the CCTV Headquarters in Beijing (his largest work to date).
