(1905-73)
Wagner was born in Germany (some sources list Mexico), and arrived in Mexico in 1930. He taught theatre at UNAM for many years. A stage director and occasional actor, he was also a TV pioneer and wrote several books on stagecraft and television drama technique. Wagner's film roles generally saw him cast as sinister foreigners (due to his German accent).
