In 1862, the Bureau of Engraving and Printing, the agency responsible for making those little pieces of paper coated in chlorophyll, better known as money, is founded. The bureau began as a relatively humble enterprise: housed in the basement of the Treasury Building, the original "money factory" had a staff of six who didn't print a single note, but instead separated the bills produced by private companies. The bureau started printing notes in 1863, and by 1887, had assumed full responsibility for producing the nation's currency. Along the way, the bureau grew from six to 2,800 employees, spread over two offices in Washington, D.C., and a branch in Fort Worth, Texas. Today, the bureau annually churns out approximately 6.5 billion notes worth $80 billion.
