Back in Warsaw, he founded and led a chamber orchestra specialised on music of the Vienna Classic (1915 to 1920).

According to his students and colleagues, Pullman was a visionary musician; his desire for a kind of revelatory ensemble playing led him to make use of the widest possible range of string tone, to demand a perfect legato, and to search out highly unorthodox fingerings to match his conceptions of phrasing.

Rehearsals were intense and long; however, they functioned as rolling all-day affairs where members came and went as their schedules permitted.

[4][5] In August 1939, he visited Warsaw in an attempt to sell a house belonging to his wife, and was trapped there by the German invasion.

Pullman was transported to Treblinka extermination camp in early August 1942, and like him, all of the members of the orchestra were presumed to have been killed.
