Excerpt from an NBC Radio broadcast on December 7, 1941. Hans von Kaltenborn (July 9, 1878 – June 14, 1965), generally known as H. V. Kaltenborn, was an American radio commentator. He was heard regularly on the radio for over 30 years, beginning with CBS in 1928 and NBC in 1940. He was known for his highly precise diction, his ability to ad-lib, and his depth of knowledge of world affairs. Kaltenborn had very specific views about radio's role in presenting the news. Later in life he wrote on the subject in many of his books. He was one of four journalists who portrayed themselves in the 1951 film The Day the Earth Stood Still. Kaltenborn also appears as himself in the 1939 Frank Capra film Mr. Smith Goes to Washington. WIKIPEDIA BIO
