In 1963, Joseph's aunt Alicia Patterson died, and the Albrights returned to Long Island with the notion of Joseph taking over the family newspaper business. In 1967 Albright gave birth to another daughter, Katherine Medill Albright. She continued her studies at Columbia University's Department of Public Law and Government. (It was later renamed as the political science department, and is located within the School of International and Public Affairs.) She earned a certificate in Russian, an M.A. and a Ph.D., writing her master's thesis on the Soviet diplomatic corps and her doctoral dissertation on the role of journalists in the Prague Spring of 1968. She also took a graduate course given by Zbigniew Brzezinski, who later became her boss at the U.S. National Security Council.
