In 1844, John Schwartz, a Flemish traveler, was the first Euro-American to permanently settle in the area of West Sacramento, which at that time was part of Mexico. He built a shack on the west bank of the Sacramento River six miles (10 km) south of its connection with the American River. John, with the help of his brother George, founded a salmon fishery along the river. In addition to the fishery, they also found the soil to be fertile and began farming and raising livestock.
