The long-running Jewish Theological Seminary radio series “The Eternal Light” usually drew from an older text, but it did feature a crusading newspaper in at least one episode, “The Rabbi with Ink-Stained Hands,” which the inspirational-drama program broadcast more than once.
The 1960 broadcast of “The Rabbi with Ink-stained Hands”:
The broadcast dramatizes the life of Rabbi David Einhorn, an anti-slavery crusader in 1850s Baltimore before being forced to flee to Philadelphia when a mob destroyed his newspaper, Sinai.
The murder of Presbyterian minister and abolitionist publisher Elijah Lovejoy is also mentioned in the story.
The Old-Time Radio Researchers Library has versions of the program from 1956 and 1960. I am browsing the long running series (1944-1962) for other episodes featuring journalists.
So far, I haven’t found references to prominent publishers of Jewish ancestry Adolph Ochs (The New York Times) or Joseph Pulitzer (The New York World), but the program dealt with moral ideals, not just Jewish ancestry. As for newspaper-related episodes, there is one involving the non-Jewish Ben Franklin (played by Ralph Bellamy), waxing nostalgic about his printing appenticeship and first “Silence Dogood” columns. And there’s another ecumenical item about Gandhi, although not focused on his newspapering.
