Werner Klemperer (Cologne, Germany, March 22, 1920 – December 6, 2000 in New York City) was a German actor.

Born into a musical family, his mother was Johanna Geisler , a soprano, and his father the conductor Otto Klemperer. A Jew, his family fled the Nazi regime in 1933, making their way to Los Angeles, California in the United States.

Klemperer began acting in high school, and, although an accomplished concert pianist, he enrolled in acting school in Pasadena before joining the U.S. Army to fight in World War II. While stationed in Hawaii, he joined the army's Special Services unit, spending the next few years touring the Pacific entertaining the troops. At the end of the war, he worked on Broadway and the advent of rapid growth in the television industry opened new doors to him. Most remembered as Colonel Klink in Hogan's Heroes, which ran on CBS from 1965 to 1971, Klemperer was very conscious of the fact that he was playing a German officer affiliated with the Nazis, and agreed only to play Klink on the condition that he would be portrayed as a fool and that he never succeeded. For his performance, Klemperer received four Emmy Award nominations for best supporting actor in each of the show's six seasons, winning in 1968 and again in 1969.

With his famous father’s passing in 1973, Werner Klemperer felt confident enough to enter into a musical career as an opera baritone and a singer in Broadway musicals, earning a Tony Award nomination for his performance in Cabaret. A member of the Board of Directors of the New York Chamber Symphony , Werner Klemperer served as a narrator with many other U.S. symphony orchestras.

Werner Klemperer passed away on December 7, 2000. His body was cremated and his ashes were scattered at sea.
