An expert on the life of Franklin D. Roosevelt will join the History faculty this year as a full professor, Dean Bundy announced yesterday.

Frank Freidel, Jr., a biographer of Roosevelt, will become professor of History effective July 1. He will become the second expert on Roosevelt in the University. At present Arthur M. Schlesinger, Jr. '38 is working on an independent study, "The Age of Roosevelt."

Freidel, now an associate professor of History at Stanford University, has published two volumes of a projected six-volume biography of Roosevelt. He holds both A.B. and A.M. degrees from California.

Neither Freidel nor Schlesinger will limit his professional research to the Roosevelt period, Bundy said.

He did not say, however, what courses Freidel would teach. At Stanford, he teaches "The Age of Big Business, 1877-1919," and an introductory course in United States History, as well as a course specifically on the Roosevelt era. He has published "Francis Lieber, 19th Century Liberal," a biography of an authority on political philosophy and military law.
