 One of the first serious post @-@ war studies of Meyerbeer and grand opera was Crosten 's 1948 book Grand Opera : An Art and a Business which laid out the themes and standards for much subsequent research . A major contribution to revival of interest in Meyerbeer was the work of the scholar Heinz Becker , leading to the complete publication , between 1960 and 2006 , of Meyerbeer 's complete diaries and correspondence in German , which are an important source for musical history of the era . The English scholar Robert Letellier has translated the diaries and undertaken a wide range of Meyerbeer studies . Not least , the establishment of a ' Meyerbeer Fan Club ' in America has stimulated interest .
