E. G. Marshall (born Everett Eugene Grunz, June 18, 1914 – August 24, 1998) was an American actor, best known for his television roles as the lawyer Lawrence Preston on The Defenders in the 1960s and as neurosurgeon David Craig on The Bold Ones: The New Doctors in the 1970s. Among his film roles he is perhaps best known as the unflappable, conscientious "Juror #4" in Sidney Lumet's courtroom drama 12 Angry Men (1957). He played the President of the United States in Superman II (1980). Marshall was also known as the host of the radio drama series, CBS Radio Mystery Theater (1974–82). Marshall was born in Owatonna, Minnesota, the son of Hazel Irene (1892–1975) and Charles G. Grunz (1882–1959). His paternal grandparents were German. During his life, he chose not to reveal what "E. G." stood for, telling most people it stood for "Everybody's Guess," but it can be observed the initials match Everett (or Eugene) Grunz. According to the Social Security Death Index, his Social Security card showed his full name as: "E G Marshall". He attended both Carleton College and the University of Minnesota.
