Fritz Lissauer (1874-1937) was a German-Jewish composer, the full score of his Violin concerto op.100 (1922/23) can be downloaded free of charge from my website:

Ah, as with Gernsheim and Weinberger, I see that the National Library of Israel has a Lissauer archive. Good on them! ("Trio fur Klarinette, Fagott und Klavier. Op. 113 (manuscript) 1934." - intriguing :) ... also a manuscript symphony (http://www.worldcat.org/title/symphonie-manuscript-1912/oclc/875103723) (oh drat, not quite complete, but.) dated 1912 @ same archive.)
