Nearly 1,100 Wyoming servicemen, representing every county, died in World War II. As in other states, Wyoming’s people gained a stronger sense of being part of the nation thanks in part to war bond drives, scrap metal drives, book drives, victory gardens—and their loved ones’ service at home and overseas.
Oil refining in Wyoming began in 1895. By the 1920s the state boasted 16 refineries, with Standard Oil’s plant at Casper by far the largest. Production tracked oil booms and busts throughout the 20th century, culminating in the 1991 shutdown of Casper’s Amoco (formerly Standard) Refinery. Six refineries remain in production today.
