The Story:
The first jeans came in two styles, indigo blue and brown cotton "duck." Unlike denim, the duck material never became soft and comfortable so it was eventually dropped from the line. Although denim pants had been around as work wear for many years, historically dating back to England in the 1600s with a fabric there called denim, it was the first use of rivets that created what we now call jeans. "Waist overalls" was the traditional name for work pants, which is what these first jeans were called. The word jeans became more popular around 1960 when the baby-boom generation adopted the term for its favorite type of pants. How were blue jeans invented is a simple story.

Levi Strauss came to San Francisco in 1853, at the age of twenty-four, to open a west coast branch of his brothers' New York dry goods business. He had spent a number of years learning the trade in New York after emigrating there from his native Germany. He built his business into a very successful operation over the next twenty years, making a name for himself not only as a well-respected businessman, but as a local philanthropist as well.

One of Levi's many customers was a tailor named Jacob Davis. Originally from Latvia, Jacob lived in Reno, Nevada, and regularly purchased bolts of cloth from the wholesale house of Levi Strauss & Co. Among Jacob's customers was a difficult man who kept ripping the pockets of the pants that Jacob made for him. Jacob tried to think of a way to strengthen the man's trousers, and one day hit upon the idea of putting metal rivets at the points of strain, such as on the pocket corners and at the base of the button fly.

These riveted pants were an instant hit with Jacob's customers and he worried that someone might steal this great idea. He decided he should apply for a patent on the process, but didn't have the $68 that was required to file the papers. He needed a business partner and he immediately thought of Levi Strauss.

In 1872 Jacob wrote a letter to Levi to suggest that the two men hold the patent together. Levi, who was an astute businessman, saw the potential for this new product and agreed to Jacob's proposal. On May 20, 1873, the two men received patent no.139,121 from the U.S. Patent and Trademark Office. That day is now considered to be the official "birthday" of blue jeans.

With the patent secured, Levi hired Jacob Davis to oversee production of the riveted pants at the Levi Strauss & Co. San Francisco plant. Sometime during 1873, the first riveted clothing was made and sold. (the exact date was lost along with the company records in the 1906 San Francisco earthquake and fire). Jacob Davis was in charge of manufacturing when Levi Strauss & Co. opened its two San Francisco factories.

In 1875 Levi and two associates purchased the Mission and Pacific Woolen Mills from the estate of former silver millionaire William Ralston. Much of the mill's fabric was used to make the Levi Strauss & Co. "blanket-lined" pants and coats.

The denim for the riveted work pants came from the Amoskeag Mill in Manchester, New Hampshire, a company known for the quality of its fabrics. Within a very short time, all types of working men were buying the innovative new pants and spreading the word about their unrivaled durability. Hard to imagine that back in 1885, when denim first established itself as a reliable work wear cloth for a working man's garment that a pair of Levi overalls cost $1.25. Brand new.

Holding a patent on this process meant that for nearly twenty years, Levi Strauss & Co. was the only company allowed to make riveted clothing until the patent went into the public domain.. Around 1890, these pants were assigned the number 501, which they still bear today. When the patent expired, dozens of garment manufacturers began to imitate the original riveted clothing made popular by Levi Strauss & Co.

In the 1950s, high school kids put them on as a radical way of defining themselves, of wanting to look and be more adult and dangerous and rebellious against adults because adults didn't wear jeans. A decade later, blue jeans became a symbol of egalitarianism, a uniform for young adult baby boomers waging a generational war. In the 1970s Me Decade and the beginnings of celebrity culture surfaced, jeans were definitely about being sexy and all about fashion.

In 1980 came the controversial Calvin Klein ad slogan heard around the world. Who can ever forget 15-year-old Brooke Shields (barely old enough to get her driver's permit) purring into living rooms "Nothing comes between me and my Calvins"? As Vogue magazine editor in 1988, Anna Wintour's first cover was a pair of Guess? stonewash jeans teamed with a Christian Lacroix bejeweled top. The 1990s took denim onto country-western dance floors, onto the red carpet and created puzzling fashion styles from born-to-be-torn grunge jeans to baggy hip-hop jeans to rock star appeal all adding to the confusion of casual Fridays.

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. 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.

"Nothing comes between me and my Calvins." - Brooke Shields, 1980 controversial Calvin Klein ad


  • An original pair of Levi's jeans is part of the permanent collection of the Smithsonian Institution in Washington, D.C.
  • The word, 'jeans,' came from the cotton workpants worn by sailors from the port of Genoa, Italy, who were themselves known as Genes.
  • The  jeans market has grown to be a $14.6 billion industry
  • On May 20, 1873, Jacob Davis and Levi Strauss received patent #139,121 from the U.S. Patent and Trademark Office.
  • Levi's 501 jeans are the original Shrink-To-Fit, button-fly blue jeans first created in the 1800s. 501 jeans are the oldest and best selling product of Levi Strauss & Co. The number 501 was assigned to the jeans around 1890.
  • In 1885 a pair of Levi waist overalls cost $1.25. Brand new. By the turn of the century, the company charged $8.50 for a pair of blue jeans.
  • In 1997, Levi Strauss & Co. paid $25,000 for a pair of 100 year old jeans (for their museum) found in an old Colorado mine, which is the oldest known pair of Levi jeans.
  • Seven out of 10 Americans say jeans are their first pick for casual wear.
  • Levi Strauss & Co. currently makes 501 jeans in approximately 108 sizes and 20 finishes/fabrics.
  • A typical pair of Levi's 501 jeans takes about 1 3/4 yards of denim, 213 yards of thread, five buttons and six rivets.
  • There are 37 separate sewing operations involved in making a single pair of Levi's 501 jeans.

  • The double row of stitching on the back pockets - known as the Arcuate stitching design - is the oldest apparel trademark still in use today. It was first used in 1873. During World War II, the Arcuate stitching design was painted on the pockets due to government rationing of essential items such as thread.
  • Rivets were first used on 501 jeans in 1873 because miners complained that their pockets ripped under the weight of ore samples. The early jeans had rivets on the front and back pockets. Rear rivets were covered beginning in 1937 because of complaints that the rivets scratched school desk chairs and saddles. Since 1967, reinforced stitching has replaced the back pocket rivets.
