Louis Kahn is known for his contributions to architecture as both a visionary and a professor, having famously designed the Yale University Art Gallery along with countless commissions around the U.S. for museums, libraries, and research institutes. His profession is easily readable in his drawings, which usually feature landscapes with man-made structures as subjects. Kahn was rigorously trained in the Beaux-Arts tradition with an emphasis on traditional drawing. His characteristic aesthetic, however, is defined by loose marks and abstracted representations, influenced in part by Giorgio de Chirico. He developed this style when he traveled through Europe after leaving art school, making sketches as he went sightseeing; many of his artworks are fragments of a lifelong travelogue.
