Eli Whitney

Explanation:

He (Eli Whitney) was born on December 8, 1765, in Westborough, Massachusetts. while growing up, Whitney, whose father was a farmer, proved to be a talented mechanic as well as inventor. He also designed object and built as a youth were a nail forge and a violin. In 1792, after graduation from Yale College (now Yale University), Eli Whitney headed to the South. He purposely planned to work as a private tutor but instead accepted an invitation to stay with Catherine Greene (1755–1814), the widow of American Revolutionary War (1775-83) general Nathanael Greene, on her plantation, known as Mulberry Grove, near Savannah, Georgia. While there, Eli Whitney learned about cotton production–in particular, The Patent-law issues prevented him from ever significantly profiting from the cotton gin; Moreover, in 1798, he secured a contract from the U.S. government to produce ten thousand muskets in two years, the amount that had never been manufactured in such a short time. Eli Whitney promoted the idea of interchangeable parts: standardized, similar parts that would make for faster assembly as well as easier repair of various objects and machinery. By that time, guns were typically built individually by skilled craftsmen, so that each finished device was unique. Though it ultimately took Whitney some 10 years, instead of two, to fulfill his contract, he was credited with playing a pioneering role in the development of the American system of mass-production.

In 1817, Eli Whitney, then in his early 50s, married Henrietta Edwards, with whom he would have four children. He died on January 8, 1825, at age 59.

1%= 120/100=   1.2

9%   = 1.2 x 9=     10.8
