Alfred Einstein, one of the great musical scholars of this century, was the editor of the third edition of Kochel's Mozart catalogue. His tremendous three-volume history The Italian Madrigal, summing up forty years of work, is a veritable monument of Renaissance music. He was equally at home in the Romantic world, as he demonstrated in his Music in the Romantic Era.
The late Paul Henry Lang ranks among the century's most eminent musicologists. A longtime faculty member at Columbia University, he also served as editor of the Musical Quarterly and as music critic for the New York Herald Tribune.
