Alfred Ottokar Lorenz (11 July 1868, Vienna – 20 November 1939, Munich) was an Austrian-German conductor, composer, and musical analyst. His principal work is the four-volume Das Geheimnis der Form bei Richard Wagner, which attempts to comprehensively analyze some of Richard Wagner's best-known operas. Lorenz's work reflects to a great extent his sympathy with Nazi ideology, and has only recently been discredited by scholarship. Source: Wikipedia (en)
