This firm was founded by Fritz Müller (1872–1944) in 1898 and is still operating. It has had three main locations: Strassburg (since 1918 Strasbourg, France) 1898-1918, Karlsruhe in the inter-war period and Heidelberg from 1938. Fritz Müller's son Willy Müller (1900–1985) also worked in the firm from the 1930s. The founder's grandson, Peter Ferdinand Michael Müller, briefly ran the publishing house after his father’s death, then sold the company and its publishing archive to Bärenreiter of Kassel in 1988.
The catalog has had two distinct phases. For the first 20 years of the company, until 1918, the emphasis was on contemporary composers, such as Koessler, Marteau, J Bloch, Dalcroze, Katz and Thuille, while since the first world war, in addition to contemporary items, there have been many Baroque works,
|10||Thuille||Cello Sonata, Op.22 (sc&pt)||1902|
|81||Bloch||4 Easy Pieces, Op.36 (no.4, sc&pt)||1903|
|116||Marteau||Fantasiestück, Op.3 (vn, pf red. ed Valentin)||1904|
|221||Marteau||Clarinet Quintet, Op.13|
|425||Aeschbacher||Piano Trio, Op.2 (sc&pts)||1913|
|537||Dusch||Piano Quintet, Op.14 (sc&pts)||1939|
The von Dusch is "F.M. 537 S.M." from the Fritz Müller, Süddeutscher Musikverlag and they may not have the same plate table (S.M-V 537 may be a different item than FM 537 SM.) - note that otherwise from 425 to 537 is a huge falloff.
