In the Leonardo De Lorenzo's "My complete story of flute", Kulau certainly had been written Kuhlau "Friedlich Kuhlau(1786-1832), German flutist, a composer of many operas and music for flute. A Danish music supervisor. He is called as"Beethoven of flute". In the H. Macaulay Fitzgibbon's "The story of the Flute" in 1914, he told "The greatest composer and flutist was Kuhlau. His classical works justly gave him the honorable title of Beethoven for Flute. Many of his works had undoubtedly influenced the greatest composer, Beethoven. Beethoven for flute is proper for him".
Please tell me by E-mail if someone said it before Fitzgibbon.
