Professor At University of Chicago

When the fellowship at Trinity College ended in December 1936, Chandra moved to USA.

In February 1936, Otto Struve, the director of the Yerkes Observatory, part of the university of Chicago, invited him to give a lecture there. At that time, Yerkes was one of the most important observatories in the world. Struve was so greatly impressed by Chandra that he offered him a position at Yerkes Observatory right after his lecture. Harvard University also had offered him a post, a three-year appointment as a member of its prestigious Society of Fellows. Chandra accepted the position at Yerkes. And he assumed that position in January 1937.

In 1938, he joined as an assistant professor of astrophysics at the  University of Chicago and rose to become Morton D. Hull distinguished service professor of astrophysics in 1952.
