Named because a storekeeper had an opinion
Before it was Ripon it was Murphy's Ferry, a gold rush river crossing. In 1857 William Hiller Hughes claimed 160 acres by the Stanislaus and the place became Stanislaus City. When the Southern Pacific came through in 1872, Hughes handed the railroad the right-of-way and the depot, and they built a small station called Stanislaus Station.
Hold that next to Lathrop, twelve miles north. Lathrop exists because Leland Stanford had a right-of-way dispute with Stockton and routed the railroad around the city. Ripon exists because Hughes simply gave his away. Two towns, twelve miles apart, founded on opposite answers to the same question.
Then in 1874 a man named Amplias B. Crooks arrived from Ripon, Wisconsin, opened the first store, and applied for a post office. He did not care for the name Stanislaus Station, so he asked that it be called Ripon after his hometown, and on December 21, 1874 it was. Wisconsin's Ripon was itself named for Ripon in North Yorkshire, so the name traveled Yorkshire to Wisconsin to here on the strength of one man's preference.
The almonds came from water. Before the South San Joaquin Irrigation District formed in 1908 this was dry grain farming and cattle grazing. Irrigation brought alfalfa, dairy, grapes, peaches, apricots, figs, olives, corn, melons, tomatoes, and almonds. The crop the whole region is now identified by was introduced near Ripon on a trial basis around 1900 by J. P. Watkins. An experiment became an identity, and eventually a nickname.
Ripon incorporated on November 27, 1945, seventy-one years after it got its name. Growth waited until 1998, when the areas north of the Golden State Freeway were slated for housing, and the 99 still reads as the line between the old town and the new one. A 2003 interchange rebuild brought the truck stops, restaurants, and shopping center that face the freeway today. Gospel artist Walter Hawkins, a Grammy winner, came from here.
