- More about Eli Whitney from the Book of Knowledge:
A number of inventions had come forth which improved the method of turning cotton into cloth. Finished products were being manufactured faster than ever, and this raised a great demand for more and more raw cotton. The need brought forth the man who supplied the answer. He was Eli Whitney, born at Westborough, Massachusetts, in 1765.
Whitney worked to pay most of his own expenses through Yale University and was graduated from that school in 1792. He went to the southern states with the purpose of teaching, turned to studying law and finally set to work on inventing.
The cotton-picking procedure at that time was a slow, difficult process, due to the fact that the cotton had to be separated from the seed by hand….
A small patch of cotton was grown on almost every southern farm, but the great difficulty was to separate the fiber from the seeds. It had to be done by hand, and it was the task of the slaves, and sometimes of the children of a family, to separate a shoeful of the cotton between supper and bedtime. A whole day’s work was only about four pounds.
Whitney visioned a machine that could do the work faster…. He succeeded in producing the mechanical separator known as the cotton-gin. Various lawsuits defending his rights as inventor cut his profits on the gin to almost nothing.
He set up in business, therefore, as a maker of firearms, and produced great quantities of guns cheaply and well. It was Whitney who introduced the system of division of labor, by which each part was made separately. He seems also to have started the idea of standardization, or changeability, of parts. He died a wealthy man.
