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.
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.
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.
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.
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.
