Cannizzarite is sulfide of lead and bismuth and found in volcanic fumaroles at depths reaching 510 degrees F. It also occurs in many other geological environments including vein quartz with gold and sulfide veins. Identifican of the mineral dates back to 1924 and is named after the Italian scientist Stanislao Cannizzaro, who worked on the calculations of atomic weights with what was called the "Cannizzaro reaction". Cannizzarite was thought to be a variety of Galenobismuthite, a closely related mineral.
As you can see the vial dated 1927, not long after the discovery. This is the type locality.
