He helped cover the events and exhibitions at various stamp shows and other philatelic events. At the New York Herald Tribune he was the stamp and coin editor from 1933 until he died in 1939.
Ralph Barry discussed the pleasures and techniques of the hobby of stamp collecting on various media, including on radio. He authored the book “A Glossary for the Stamp Collector” in 1936, and it was updated and revised in 1938 and 1940.
