No item of clothing is more American than the blue jeans invented and perfected in the last quarter of the19th century by Jacob Davis and Levi Strauss These two visionary immigrants, turned denim, thread and a little metal into the most popular clothing product in the world - blue jeans.

Jacob Youphes was born in 1834 in Riga Latvia. He came to the US and then to San Francisco in the 1854 and changed his name to Jacob Davis. He operated a tailor shop in New York City and Augusta, Maine. In 1856, he arrived to San Francisco and shortly thereafter moved north to Weaverville to work as a tailor. In 1858, he left California for western Canada where he lived for nine years, married, and started a family.

Davis returned to San Francisco by ship from Victoria, British Columbia, in January 1867. He soon traveled to Virginia City, Nevada where he first opened a cigar store, but within three months he again turned to his trade as a tailor. In June 1868, he relocated once again, this time to the fledgling railroad town of Reno Nevada. Investing in a brewery, he lost virtually everything. By 1869, he had opened a tailor shop on the town's main thoroughfare, Virginia Street. He began fabricating wagon covers and tents from a rugged off-white duck cloth sold by San Francisco's Levi Strauss & Co.

He moved around the West extensively trying to make a living through the 1860s. In 1868 Jacob settled in Reno, Neveda tailoring fine clothing and manufacturing utilitarian items such as tents and horse blankets from "duck" (a sturdy cotton fabric) with copper rivets for added strength.

In the late 1870s a woman came to him for a pair of "cheap" pants for her "large" husband who had the habit of going through pants rather quickly. Having found that thread alone did not always adequately hold the pockets onto work pants, Jacob decided to try out rivets, which had proven their worth on horse blankets on the pockets for these pants.

By 1871 Davis was routinely using rivets on the pants he made, first on duck, soon after on denim, and was beginning to be imitated by other tailors. He contacted Levi Strauss, his fabric supplier, to help him apply for a patent.

The patent application was rejected several times by the patent office but finally granted jointly in the names of Davis and Levi Strauss & Company on May 20, 1873. By then, Davis had already departed Reno for San Francisco to operate what amounted to an elaborate tailor shop for Strauss (he delivered his first pants to the company on June 2) and then, when more output was needed, to open and run a new Strauss manufacturing plant. After the expiration of the patent in 1890, Strauss began cranking out a less expensive version of Double XX to compete with a sudden flood of blue jeans on the market made by other companies.

Strauss was a regional company, and for decades jeans were a very small part of its business and were sold mostly to workers. (Jacob Davis went to New York in 1876 and opened a plant, J. Strauss, Brother and Company, which shut down after Jonas Strauss's death nine years later.) One company official was quoted saying, "To be honest, at first we didn't look beyond the cowboy/miner/laborer market in California, Arizona, Nevada, and maybe Colorado and Utah and, in a minor way, Oregon and Washington."

Davis remained with Strauss the rest of his career, taking over shirt lines as well as pants, and continued to supervise the Levi Strauss factory until his death in 1908, he was succeeded in the job by his son Simon Davis, who ended up running the company. Simon was instrumental in the company's rebuilding after the 1906 earthquake and designed a coverall that became the company's first nationally marketed product.

The term "Levi's," though, was not the company's--it originated with the public, just as the public invented the term "coke" for Coca-Cola. But when the public started referring to the pants generically as "Levi's," the company quickly trademarked it. Unfortunately, because Davis didn't insist on his name being included in the product name, Levi Strauss' name alone became a synonym for the pants, leading to the spread of a myth that Strauss invented them.

While Levi Strauss sold work jeans, it was an obscure, Jewish tailor working at 31 Virginia Street in Reno Nevada who added the rivets. A federal patent-infringement case filed in February 1874 in the U.S. Circuit Court of California, and housed in the National Archives regional branch in San Bruno, south of San Francisco, contains the facts.
