SharonC brought up David Hochstein for Memorial Day (My Forum Blog - SharonC) and I thought it was worthwhile to share a little more about him, because he had popped up in my YT suggestions not too long ago. 

David did die young in WWI (was given a deferment, opted instead to serve), but he accomplished quite a bit & left a wonderful legacy.  He recorded a piece of Kreisler's, Cesar Cui's, and his arrangement of a Brahms waltz - all the year before he died.  He also left some compositions for violin & piano, and planted the seed of music education for the underprivileged - the David Hochstein Music School was started in his memory. 

David Hochstein gave his last public performance in Nancy (France) on the same day he received his Commission in the US Army's Infantry... a week later he was killed by a bomb (only 26yrs old).   

I did find a couple of his scores on the Internet Archive.  His violin score for Menuet (In olden Style) starts in Eb, changes to Ab, then ends back in Eb.  His Ballad for Violin and Piano is not long, but more challenging.  The key signature is G, but there are quite a few other sharps, flats and naturals to keep track of, as well as double stops and a couple time signature changes.  Too bad there are no recordings of himself playing these.

Marcos Kreutzer's video 'Remembering David Hochstein' - Marcos starts with the arrangement David made for the Brahms Waltz in A-Flat Major, Op. 39 No. 15.  He plays David's Menuet starting at 3:22 (like it shows where he shifts).  At 6:55 he starts Hochstein's Ballad, but the performance is out of sync with the audio.
