Pittsburgh PA radio station KDKA broadcasts the first religious program over the airwaves: a vesper service of Calvary Episcopal Church. The senior pastor, unimpressed by the landmark broadcast, didn't even participate in the service, leaving his junior associate to conduct it. The two KDKA engineers (one Jewish, the other Catholic), were asked to dress in choir robes to be less obtrusive. Today religious broadcasting is a multi-billion dollar industry.
Personal Postscript — Pittsburgh, my hometown from birth to age 18, was the scene of many firsts: first commercial radio station; first TV program by my neighbor, Mr. Fred Rogers; and the city in which I first visited a natural history museum, Phipp’s conservatory, Carnegie library, Highland Park zoo, Buhl planetarium, Heinz pickle factory, Pirates game at Forbes Field, Kennywood Park, Mt. Washington Incline, Santa Claus at Gimbel’s, train and streetcar rides, Fort Pitt, Cantor’s delicatessen, and countless other childhood memories. Ah, I wish I were a child again. The child really is the father of the man.
