Chuck Trantham recalls that Jack collected nissonite at the type locality in San Benito County, California, with Charles Chesterman, pumpellyite and omphacite near Cazadero, California, with George Switzer and Al McGuinness, and parahopeite at Broken Hill, Zambia, with Al McGuinness and Luis Leite.
