Beethoven regarded Luigi Cherubini as the father of his brothers, but not Franz Schreker.
Franz Schreker (originally "Schrecker"; 23 March 1878, Monaco  21 March 1934, Berlin) was an Austrian composer, conductor, teacher and administrator. 
Luigi Cherubini (] ; 8 or 14 September 1760  15 March 1842) was an Italian composer who spent most of his working life in France. 
 Beethoven regarded Cherubini as the greatest of his contemporaries.
