Vladimir Aleksandrovich Pozner was a Russian Jewish émigré to the United States.

During World War II he spied for Soviet intelligence while being employed by the United States Government.

The Pozner family fled Soviet Russia after the Bolshevik Revolution, and Vladimir Pozner became a Communist sympathizer while living in Europe.

In 1943 he headed the Russian Section of the film department of the U.S. War Department. Pozner was a frequent contact of Louise Bransten.

Vladimir Pozner’s cover name as identified in the Venona project by NSA/FBI analysts is «Platon» («Plato»).

Vladimir Pozner and his family moved to East Berlin and later to Moscow in the early 1950s.

Pozner’s son, Vladimir Vladimirovich Pozner, spoke internationally on behalf of Soviet agencies, and, after the collapse of the Soviet Union, came to be treated in the U.S., under the name Vladimir Posner (having Anglicized the surname), as an independent journalist.
