Thurman, and Herbert, took over operations of Desert Center, and Stanley eventually purchased the town from his father. Stanley ran it for decades, adding a hamburger stand and the Stanco gasoline station. Early prepaid health insurance In the early 1930s, Dr. Sidney R. Garfield, who had just graduated from University of Southern California, went to visit a former classmate with a practice in Indio. The practice was thriving to capacity, while Garfield was nearly without business in Depression-era Los Angeles. Garfield's friend explained that he was the closest doctor (50 miles) to 5,000 men digging the Colorado River Aqueduct under direction of The Seven Companies, Inc. The project site's headquarters was just southeast of Desert Center. Garfield borrowed money from his father and constructed a 4-bed clinic near the construction site. The clinic was cooled by an ammonia air-conditioning system and at the time was the only air-conditioned building between Riverside and Phoenix. Garfield would treat the men, who would promise to pay on payday, but who would usually go to Blythe or Indio and drink their paychecks. Within a year, Garfield was broke and announced that he would pull up stakes. Hearing this, Henry J. Kaiser, whose division of the Six Companies, Inc. was building the stretch of the Colorado River Aqueduct through the Desert Center vicinity, visited Garfield at his clinic. His idea was to take a nickel a day out of each man's paycheck to prepay for that man's future medical treatments, should an injury occur while he was working. If the man wanted to be covered for the remainder of the day, after work hours, another nickel would be deducted. If the man had a wife and/or children he wanted to cover, this would cost another nickel. Within a short time, Garfield had a steady income stream and things improved for him immensely. When the aqueduct project was finished, Kaiser's next venture was the construction of the Grand Coulee Dam, and he took Garfield with him to manage the workers' health care, but this time there were 50,000 men, not just 5,000. Garfield's Contractors General Hospital evolved into Kaiser Permanente, the largest managed health care system in the world, but its origins are in Desert Center. In 1992 a roadside historical marker at the site was unveiled by Garfield's sister next to the grocery honoring Desert Center as the birthplace of Kaiser Permanente. General Patton –
