On this day, two months to the day after its first broadcast, KDKA aired the
first religious service in the history of radio. It was undertaken by Westinghouse
to test its ability to do a remote broadcast far from a radio studio. Pittsburgh’s
Calvary Episcopal Church was chosen because one of the Westinghouse
engineers happened to be a member of the choir and made the arrangements.

The junior pastor, Rev. Lewis B. Whittemore, preached because the senior pastor
was leery of the new medium. The technicians (one a Jew, one Catholic) were
outfitted with choir robes in order to keep them from distracting the congregation.

The modern holiday of Mother’s Day was first celebrated in 1908, when Anna
Jarvis held a memorial for her mother at St Andrew’s Methodist Church in
Grafton, West Virginia. Today St Andrew’s Methodist Church now holds the
International Mother’s Day Shrine. Her campaign to make "Mother’s Day" a
recognized holiday in the United States began in 1905, the year her mother,
Ann Reeves Jarvis, died.
