Hamburger was part of the early Jewish, merchant community in the 
Cariboo region with 
J. Boas, 
S. D. Levi, David Solokosky, Herman Lewin, Isadore Braverman, and Herman Schultz.
1From notices in the Cariboo Sentinel, it appears that Hamburger worked in conjunction
                     with 
Levi and 
Boas as a handler of investments.
2 Bankruptcy court reports show Hamburger’s frustrations with a bankrupted estate he
                     was trying to collect money from; the judge commented on the poor accounts Hamburger
                     kept and tossed the case.
3Hamburger appears in this 
despatch, wherein he reportedly borrows $2000 from 
Ivel (Joel) Abbott. Additionally, he witnesses that 
out of one little crevice, ... he, Abbott, took 60 ounces out of it.
