First jeans ever made?

No item of clothing is more American than the blue jeans invented in 1873 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. 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, blue jeans.
