“The Death of Socrates” on a You Are There episode.

The series “You Are There” was a CBS network program in which modern
news reporters intervened in American and world historic events as recreated
by actors. It was first heard on radio, and then moved to television where it ran
from 1953-1957. The show was written by a number of blacklisted writers using
a “front,” and touched on themes that were too controversial for other programs
to address directly. News icon Walter Cronkite was the regular host. Reporters
included veteran radio announcers Dick Joy and Harlow Wilcox.
