Oscar-nominated actor Robert Vaughn, the debonair crime-fighter of television’s “The Man From U.N.C.L.E.” in the 1960s, has died.

Vaughn died this morning after a brief battle with acute leukemia. The Ridgefield resident was 83. 

Vaughn’s “The Man From U.N.C.L.E.” character teamed with a soft-spoken, Russian-born agent played by Scottish actor David McCallum. U.N.C.L.E. stood for United Network Command for Law and Enforcement.

Earlier, Vaughn was nominated for an Oscar for the 1959 film “The Young Philadelphians.” He also was in the classic Western “The Magnificent Seven.”
