He returned to the VOA in 1974 as chief of policy and that same year was promoted to director of programs at the international network. He directed the VOA's programming during the U.S. withdrawal from Vietnam and the final months of the Watergate crisis.

A scholar and writer, he earned a master's degree in international public policy at the Johns Hopkins School of Advanced International Studies in Bologna, Italy, where he studied from 1964 to 1965. He was appointed dean at the School of Area Studies at the Foreign Service Institute in Arlington in 1988 and supervised more than 40 area studies courses on politics, government, economics, culture and U.S. diplomacy in eight world regions.

He retired again in 2003.

He was born John Horace Shellenberger in Amsterdam, N.Y., and grew up in Yonkers, N.Y., and Los Angeles. He graduated from Northwestern University in Evanston, Ill., in 1952.
