Edward Hunter, 75, a leader in anti-communist causes and the author of several books on "brainwashing," a term he is said to have coined, died at his home in Arlington Saturday following an apparent heart attack.

From 1964 until his death, Mr. Hunter had been editor and publisher of TACTICS, a monthly journal devoted to developments in psychological warfare and analyses of current events. He also was chairman of Anti-Communism Liaison, Inc.

He was a former newspaperman and foreign correspondent. From 1927 to 1930, he worked on English-language newspapers in Japan and China. From 1931 to 1936, he worked for the old International News Service and covered the Japanese invasion of Manchuria, the Spanish Civil War and the Italian invasion of Ethiopia.

During World War 11, he was a psychological warfare specialist with the army and with the Asian section of the Office of Strategic Services. He also was an adviser to the Air Force on psychological warfare in the mid 1950s.

His books on "brainwashing" - the use of psychological and other pressures to obtain confessions from prisoners - include "Brain-Washing in Red China," first published in 1951 and issued in a revised version in 1971, and "brainwashing: The Story of the Men Who Defied It," published in 1956. This also was published in revised form in 1971 under the title, "Brainwashing: From Pavlov to Powers."

Mr. Hunter was born in New York City. His early newspaper experience was on The Newark, N.J., Ledger, The New Orleans Item, The New York Post and The New York American.

He was married in 1932 to the former Tatiana Pestrikoff, who now lives in Greatlawn, N.Y. The marriage ended in in divorce in 1961.

Survivors include a son, Robert, of Rochester, N.Y., a daughter, Tatiana Potts, of Glenelg, Md., and seven grandchildren.
