what is today known as Beaux-Arts Classicism, a rigorous pedagogy that sought to train architects and artists in the grand tradition that began with the Greeks, passed through Rome and then the Renaissance, and emerged as the modern equivalent of humanistic philosophies. Upon returning to America, Stein joined the office of the progressive, eclectic architect Bertram Goodhue and his more eccentric partner Ralph Adams Cram in 1911 and contributed to three of Goodhue's large-scale projects of that time: the Panama-California Exposition (1915) in San Diego, California, the company town of Tyrone, New Mexico, and the master plan and individual buildings for the California Institute of Technology in Pasadena. While working on these extraordinary planning schemes he participated in the birth of modern urban design in the United States. While marginally influenced by Ebenezer Howard, the English Garden City advocate, Stein was more attuned to the planning innovations of his American contemporaries: Edward Bennett, John Nolen, and John Charles Olmsted. In 1919, Stein started his own practice in New York, and in 1921, he began his long association with fellow architect Henry Wright. The two were influential in the 1930s, designing New Town projects, sponsored by New Deal visionaries: Radburn, New Jersey, Sunnyside Gardens, Queens, and Chatham Village, Pittsburgh. In 1923, Stein also cofounded the Regional Planning Association of America (RPAA) to address large-scale planning issues such as affordable housing, the impact of sprawl, and wilderness preservation. Other founding members included Lewis Mumford and Benton MacKaye; the RPAA helped MacKaye develop his vision for what would become the Appalachian Trail. The RPAA has remained a formative and influential organization in regional planning, especially in the New York Metropolitan area. Stein served as a president of the RPAA from 1925 to 1948. From 1923 to 1926, Stein served as chairman for the New York State Housing and Regional Planning Commission. Stein travelled extensively to other countries and established friendships with among others Swedish statesman-planner Yngve Larsson. Personal life From 1928 to his death in 1975, Stein was married to stage and film actress Aline MacMahon. They had no children. Accomplishments Beginning in 1923 Stein and Henry Wright collaborated on the plan for Sunnyside Gardens, a neighborhood of the New York City borough of Queens. The low-rise pedestrian-oriented development was constructed between 1924 and 1929. It was funded by fellow RPAA officer Alexander Bing and took the garden city ideas of Sir Ebenezer
