40 Fun Facts About Cotton Gin

In a story Eli Whitney liked to tell, which animal clawing at a chicken through a fence inspired his cotton gin?

A cat reaching through a fence for a chicken came away with only feathers, Whitney said. His gin's teeth did the same job, dragging fiber through gaps too narrow for the seeds.

The 'gin' in cotton gin, the seed-removing device Eli Whitney patented in 1794, is a clipped form of which word?

Engine is the word that 'gin' clips, so a cotton gin is literally a cotton engine. The name has nothing to do with the drink.

Seeds stripped out by cotton gins yield a cooking oil; which kitchen brand, launched in 1911, was first made from it?

Crisco was hydrogenated cottonseed oil, sold from 1911 as a substitute for lard. Its early ads pitched it as more economical than butter.

The earliest known cotton gins, simple single rollers used by the fifth century, come from which country?

India had roller gins some thirteen centuries before Whitney's patent. Fifth-century Buddhist paintings in the Ajanta Caves show a single-roller gin at work.

The cotton gin, which made slave-grown cotton hugely profitable, is often cited as an indirect cause of which conflict?

The Civil War is often traced back to the gin, which revived a Southern plantation economy that had been in decline. Enslaved people in the US rose from about 700,000 in 1790 to over 3 million by 1850.

Once the cotton gin made cleaning cotton fast, which earlier step in production became the new labor bottleneck?

Picking was still slow field work, so planters who could now clean far more cotton bought more enslaved workers to harvest it. Mechanical harvesters did not arrive until the 1930s.

After patent fights left him in debt, cotton gin inventor Eli Whitney won a 1798 government contract to make what?

Muskets were a bold thing to promise, because Whitney had never made a gun in his life. The order he agreed to fill by 1800 was not delivered until 1809.

Which Secretary of State received Eli Whitney's 1793 cotton gin patent application and asked him to send a model?

Thomas Jefferson ran the young patent system from the State Department and told Whitney a working model was the only thing missing. The finished patent was signed by George Washington.

Southern planters wanted a better cotton gin in the 1790s partly because which older cash crop was losing its profits?

Tobacco had been overplanted until supply outran demand and the soil wore out. Cotton that could be cleaned cheaply offered planters a replacement.

Eli Whitney built his first cotton gin in 1793 at Mulberry Grove, a rice plantation in which Southern state?

Georgia had bought the estate for a Revolutionary War general, whose widow invited Whitney to stay. Only a bronze marker near Savannah now shows where it stood.

Eli Whitney graduated in 1792, the year before he built his cotton gin, from which Ivy League college?

Yale took Whitney at 23, older than most students, and he finished in three years. Its admissions program for non-traditional students now carries his name.

Eli Whitney built his cotton gin as a guest of the widow of which Quaker-raised Revolutionary War general?

Nathanael Greene had died in 1786, leaving his wife Catharine to run the plantation. She introduced Whitney to the men who wanted a seed-cleaning device.

Cotton gin inventor Eli Whitney is often wrongly credited with inventing which manufacturing idea that he promoted?

Interchangeable parts were already being pursued in France before Whitney took up the idea as a manufacturer. One historian concluded his famous 1801 demonstration was staged.

Cleaning cotton by hand was painfully slow; roughly how much fiber could Eli Whitney's first cotton gin clean in a day?

50 pounds or so a day came out of the early gin, where a person pulling seeds out with their fingers needed about ten hours to clean a single pound.

After a cotton gin separates fiber from seed, a press squeezes the clean cotton into what standard shipping packages?

Bales are how cotton is stored, shipped and even counted, since a harvest is measured by how many it fills. Modern gins can process up to 15 tonnes of cotton an hour.

By 1850 America grew most of the world's cotton; besides Northern mills, most of it was shipped to which country?

England wove Southern cotton into cloth in its own mills. By 1850 the United States was growing about three-quarters of the world's supply.

What disaster destroyed Eli Whitney's Connecticut cotton gin factory in the 1790s, deepening his money troubles?

A fire burned the factory to the ground while Whitney was already buried in lawsuits against gin copiers. Between the blaze and the legal bills, he was close to bankruptcy.

How was a small version of Eli Whitney's 1794 cotton gin powered, before larger ones used horses or water?

A hand crank turned the toothed cylinder, and Whitney wrote that it took one man's strength to keep it moving. Bigger gins were hitched to a horse or driven by water.

As a teenager during the Revolutionary War, cotton gin inventor Eli Whitney ran a profitable business making what?

Nails made in his father's workshop earned Whitney a profit when he was just 14. He later paid his own way to college by working as a farm laborer and schoolteacher.

Hodgen Holmes's rival cotton gin of 1796 swapped the spikes on Eli Whitney's cylinder for a row of what?

Circular saws are still what modern gin stands use to pull fiber from seed. Courts nevertheless annulled the Holmes patent and declared Whitney the inventor.

Eli Whitney first travelled to the South in 1792 to take which job, before he ever built a cotton gin?

Private tutor was the job he took because he was short of money after college. Within a year he was building a seed-cleaning device instead.

In which Connecticut city did Eli Whitney set up his cotton gin factory and die in 1825?

New Haven stayed the family's home after Whitney's death. His son, also named Eli, was instrumental in building the city's waterworks.

Inland Southern cotton was slow to clean before Eli Whitney's gin because of its sticky seeds, which were what color?

Green and sticky, the seeds clung to the fluffy fiber and had to be teased out one by one. Coastal long-fibered cotton let go of its seeds far more easily.

In Eli Whitney's cotton gin, what did a second rotating cylinder use to sweep cleaned fiber off the teeth?

Brushes on the second cylinder kept the teeth clear so the gin did not jam. An 1883 article claimed Whitney's hostess suggested them, though nothing has ever confirmed it.

The drum of Eli Whitney's first cotton gin was studded with rows of small hooked teeth made of what?

Wire hooks caught the fiber and dragged it through a screen that held the seeds back. Whitney built his first small model in only ten days.

At a cotton gin, what name is given to the cleaned fiber once it has been pulled free of the seeds?

Lint is the gin's main product, and the seed leaves as a second one. That seed is replanted or sent to a mill to be pressed for oil and meal.

Cotton fiber grows wrapped around its seeds inside the plant's rounded seed pods, which growers call by what name?

Bolls hold the fiber tightly interwoven with the seeds, which is why cleaning cotton by hand took so long. Untangling the two is the whole job of a gin.

Which painter, better remembered as an inventor himself, made the 1822 portrait of cotton gin inventor Eli Whitney?

Samuel Morse made his reputation as a portrait painter before turning to the telegraph in middle age. He painted Whitney three years before the inventor died.

Eli Whitney, later famous for the cotton gin, finished college in just three years as a member of which honor society?

Phi Beta Kappa had been founded only in 1776, so the society was barely older than the country when Whitney joined. He had started college late, at 23, after years of saving.

Which plantation manager became Eli Whitney's cotton gin business partner and later married Whitney's widowed hostess?

Phineas Miller offered to cover the whole expense of the first gin in return for a share of the profits. He married Catharine, Whitney's hostess, in 1796.

Robert Munger's 'system gin', devised from 1879, linked every stage of ginning by moving cotton along with what?

Air carried the cotton from one stage to the next, so it flowed through the gin without being hauled about. Munger said better conditions for his workers were part of the aim.

The Burton Farmers Gin, a 1914 gin house that now hosts a state cotton gin museum, stands in which state?

Texas had some 4,300 gins in 1912, when even small towns could keep one or two busy. Burton's ran until 1974 and survived with its equipment still in place.

Daniel Pratt built what became the world's largest cotton gin factory in a town named after him in which state?

Alabama's Prattville grew up around the factory, which supplied gins to every cotton-growing country. Gin equipment was made on the site for 158 years.

Modern harvesters deliver cotton to the gin in compressed blocks weighing up to ten tonnes, known by what name?

Modules sharply cut the need for trailers to haul cotton to the gin. On arrival, a feeder breaks each one apart with spiked rollers.

Researchers have studied turning cotton gin waste such as sticks, leaves and dirt into which fuel?

Ethanol could be made from the residue, but its chemical makeup varies too much from batch to batch for a steady process. Modern gins turn out the waste in substantial amounts.

Historian Joseph Roe credited cotton gin inventor Eli Whitney with inventing which metal-cutting tool around 1818?

Milling machine development is now credited to several builders working at the same time, between 1814 and 1818. Later historians judged the others more important to it than Whitney.

An original model of Eli Whitney's cotton gin from about 1800 is displayed in the US capital by which institution?

The Smithsonian shows the model in its National Museum of American History. One of its curators once likened some tales about the gin's invention to the cherry-tree story.

To collect his cotton gin patent in March 1794, Eli Whitney carried a model to which city, then the national capital?

Philadelphia was where the Secretary of State kept his office, and Whitney demonstrated the model there in person. The patent was issued on March 14.

Before debts sent him south, cotton gin inventor Eli Whitney had planned to train for which profession after college?

The law was Whitney's plan, but he set it aside to tinker through a winter and spring in a secret workshop. Court cases over his gin then swallowed much of the next decade.

The Eli Whitney Museum stands where the cotton gin's inventor built a factory in 1798, in which Connecticut town?

Hamden's museum is a hands-on workshop where students build things rather than just look. The neighborhood around it is still called Whitneyville.
