Heinrich Picot de Peccaduc, Freiherr von Herzogenberg (10 June 1843 in Graz – 9 October 1900 in Wiesbaden), known as Heinrich von Herzogenberg, was an Austrian composer and conductor (descended from a French noble family which had emigrated to Austria at the time of the French Revolution). Herzogenberg was a learned composer of clearly distinctive talents. Although he has been characterised as an epigone of Brahms, many of his compositions show little or no overt influence by Brahms, as is evident in his two string trios, Op. 27, and in his great Mass in E minor, in which the music of Wagner is said to have guided him. Some early compositions, however, which predate his encounter with Brahms and his music, do share characteristics with the older Viennese composer. It's believed that Brahms was annoyed with Herzogenberg because he was married to Elisabeth, whom he himself also liked very much. Towards the end of his life, Brahms wrote reluctantly: "Herzogenberg is capable of more than all the others."
