Theodor W. Adorno was a German-born international sociologist, philosopher, and musicologist. He was a member of the Frankfurt School of social theory along with Max Horkheimer, Walter Benjamin, Herbert Marcuse, Jürgen Habermas, and others. He was also the Music Director of the Radio Project from 1937 to 1941, in the U.S.After visiting New York City for the first time in 1937 he decided to resettle there. In Brussels he bade his parents, who followed two years later, goodbye. He said goodbye to Benjamin in Sanremo. Benjamin opted to remain in Europe, thus limiting their very rigorous future communication to letters. Adorno's relocation was enabled under an arrangement whereby part of his time was committed to the Institute for Social Research, which was then resettled at Columbia University, and the remainder as musical director on the 'Radio Project' (also known as Lazarsfeld/Stanton Analysis Programme) directed by the Austrian sociologist Paul Lazarsfeld at Princeton University.
