Ludwig Karl Koch

Ludwig Karl Koch MBE (13 November 1881, Frankfurt am Main – 4 May 1974, Harrow, London) was a broadcaster and sound recordist. An expert on recording animal sounds, he played a significant part in increasing the British public's appreciation of wildlife.

Koch was born into a music-loving family, and as a boy violinist, he was admitted to Clara Schumann's music circle. Later, he studied singing, and had a short but successful career as a concert singer. This was ended by the outbreak of World War I. As a child, he had been given an early phonograph and had recorded several animals, including the first-known recording of bird song, made in 1889.

Because he spoke fluent French, he joined military intelligence. After the Armistice in 1918, he became chief delegate for repatriation for the French-occupied zone of Germany. He worked for the German government until 1925. In 1928, he was commissioned by the German subsidiary of Electric and Musical Industries (EMI) to start a cultural branch of the gramophone industry; this coincided with a revival of his childhood interest in animals. Thus from 1929, he began recording of animal sounds again using up-to-date equipment. He invented the sound-book: attaching gramophone records to an illustrated book. Nowadays we call this multimedia.

In January 1936, Koch went on a lecture tour in Switzerland. His return flight ticket was given to him by Hermann Göring, who, as a bird and animal lover, was a fan of Koch's work. After Koch's last lecture, he was approached by a man who told him he was the Third Reich's representative in Switzerland and that he had followed Koch's lectures and written a very good report about them. It turned out the man was Wilhelm Gustloff and he was assassinated the following day. Since Koch had been seen speaking to Gustloff just hours beforehand, he became concerned about his return to Germany, that he would be accused of being involved in the assassination. He called the director of his recording company, a Nazi, who told him, "Just stay where you are. The air in Switzerland is much better than in Germany." Koch then fled to Great Britain. Sir Julian Huxley helped him to interest the ornithologist and publisher Harry Witherby in a sound-book of British wild birds. In 1936, Songs of Wild Birds was published, followed by two other sound-books by 1938 (More Songs of Wild Birds in 1937 & Animal Language in 1938). In 1937 he made recordings of the birds in the parc of the royal castle in La(e)ken (Belgium) with the aid of queen Elisabeth of Belgium. These recordings were published only in 1952, due to the circumstances of war and the Kings Question.
