Christoph Willibald Gluck and Camille Saint-Saëns, have which occupation in common?
Christoph Willibald Gluck Christoph Willibald (Ritter von) Gluck (] ; 2 July 1714 – 15 November 1787) was a composer of Italian and French opera in the early classical period. Born in the Upper Palatinate (now part of Germany) and raised in Bohemia, he gained prominence at the Habsburg court at Vienna, where he brought about the practical reform of opera's dramaturgical practices that many intellectuals had been campaigning for over the years. With a series of radical new works in the 1760s, among them "Orfeo ed Euridice" and "Alceste", he broke the stranglehold that Metastasian "opera seria" had enjoyed for much of the century.
Gustave Sap Gustave Charles Sap (21 January 1886 – 19 March 1940) was a Belgian politician and minister for the Catholic Party. Sap was also professor at the Catholic University of Leuven (Leuven, Belgium). During his professional career, he was active in the Flemish movement, agriculture and business. In 1920, he married Antoinette Gylsen, daughter of the Antwerp shipowner Henry Gylsen, and together they had six daughters and one son. Gustave Sap was the father-in-law of André Vlerick, Jan Piers and Albert De Smaele.
