John Nolen, Landscape Architect and City Planner.

From Amazon…John Nolen (1869–1937) was the first American to identify himself exclusively as a town and city planner. In 1903, at the age of thirty-four, he enrolled in the new Harvard University program in landscape architecture, studying under Frederick Law Olmsted Jr. and Arthur Shurcliff. Two years later, he opened his own office in Harvard Square. 

Over the course of his career, Nolen and his firm completed more than four hundred projects, including comprehensive plans for more than twenty-five cities, across the United States.
