Around 1937 he was robbed of his position by the National Socialists and initially worked as choir director in the southern German communities of Amorbach and Miltenberg as well as in Augsburg until he was enlisted as a soldier in 1940.
[1][2] Since 1945, at Schmid's suggestion, classical concerts have been held in the Ottobeuren Abbey and in the Kaisersaal there in the series Ottobeurer Konzerte, partly with world-famous conductors such as Herbert von Karajan and Leonard Bernstein.
Although Schmid was one of the most important co-founders of the Deutsche Mozart-Gesellschaft [de] in 1951 and was one of the supporting institutions of the Neue Mozart-Ausgabe, there was no employment for him until the 1950s.
[3] Schmid was considered to be an internationally recognized Mozart expert and was one of the most important pioneers and collaborators of the Neue Mozart-Ausgabe and its first edition director from 1954 to 1960.
On the occasion of his death the brochure [4] In memoriam Ernst Fritz Schmid (1904-1960): ein Gedenkblatt für seine Angehörigen und Freunde was published.
