Einstein in the City

On his first trip to the United States in April 1921, Albert Einstein visited The City College of New York before he proceeded to Columbia and Princeton Universities. As a result, Einstein gave his very first scientific speech in the United States at The City College, known simply and cordially to New Yorkers as ``the City.'' That visit, however, is now rarely known. This paper will investigate why Einstein came to the City, what he spoke there, and the significance and consequences of his visit. In particular, the paper will discuss Einstein's associations with Reinhard Wetzel, a physicist, and Morris R. Cohen, a philosopher, at the City.
