Early documentation officially records the name as "Fever River", an early name for the Galena River, though it does not appear that this name was commonly used. George Davenport, a retired colonel in the United States Army, successfully shipped Galena's first boatload of lead ore down the Mississippi River in 1816. Three years later, Jesse W. Shull built a trading post. The Thomas H. January family, who arrived in 1821 from Maysville, Kentucky, are considered the first permanent American settlers. The next year, the US Department of
Galena applied to pottery. Galena is a semiconductor with a small band gap of about 0.4 eV, which found use in early wireless communication systems. It was used as the crystal in crystal radio receivers, in which it was used as a point-contact diode capable of rectifying alternating current to detect the radio signals. The galena crystal was used with a sharp wire, known as a "cat's whisker" in contact with it. The operation of the radio required that the point of contact on the galena be shifted about to find a part of the crystal that acted as a rectifying
