David Hirsch[1][2] (18 May 1900 – 30 October 1982), known as Wolfgang Heinz, was an Austrian and East German actor and theater director.

Heinz was a close friend of actor Hans Otto, and under his influence became a member of the Communist Party of Germany at 1930.

[2] After the end of World War II, Heinz emigrated to the Soviet-occupied part of Vienna; at 1946, he joined the Communist Party of Austria.

[4] The theater held a communist and a pro-Soviet line, and openly defied the ban on Bertolt Brecht's works imposed in Vienna.

He appeared in more than 300 roles, and was best known for his portrayal of the title characters in King Lear, Life of Galileo, Wallenstein, Nathan the Wise and Professor Mamlock.

[6] At 1966, Heinz was appointed head of the East German Theater Artists' Association, an office he held until his death.

After the German reunification Heinz's status was retained by the city council, since his theater career in the capital begun before the communist rule and was independent of it.

[5] After his death, a Wolfgang Heinz Ring was bestowed annually to new and promising young actors by the Theater Artists' Association.
