Jack Douglas was the founder of the United Prospectors Organization (1947), originally targeted at professionals who made their livelihood by prospecting and mining. Douglas published a journal- Panning Gold- the first issue of which was issued in 1947. United Prospector's was incorporated on November 29, 1949 with Jack Douglas as President. Other officers at the time of incorporation included Walter Robertson, Stockton, CA; Tylar Jack, Reedy, CA; Speed Freeman, Olympia Field, IL; Louis Borde, Eugene, OR; Harold Mitchell, Umatilla, OR; and Glen Houston, Lodi, CA. Today UPI is "the oldest gold, gems, and minerals prospecting group of its kind."
