While documentation of the work of a select group of modernist landscape architects of the mid-twentieth century is available, little is known about the professional contributions of transitional landscape architects active in the period following World War II. Using selected projects framed by existing literature covering contemporary social, economic, political, and artistic influences, this study examines the career of one such transitional figure, Sidney Nichols Shurcliff (1906-1981). Project descriptions and analysis measure the scope of Shurcliff's work and the degree to which he contributed to the discipline and its transition to modernism, thereby augmenting the history of landscape architecture practice.
