Story

Jennings was born in 1791 in New York City. He became a seamstress and gradually opened one of the top clothing stores in New York, during which time he received a lot of complaints about their clothes always getting dirty - precisely because The material at that time was difficult to remove from the dirt by conventional methods, Jennings began researching a cleaning mixture.

He filed in 1820 and was granted a patent for "dry scrubbing" (the patent was burnt during storage). Even so, this method of using solvents to wash out clothes is well known and widely used.

Thanks to the first money earned through this patent, Jennings "bought" his family, freeing them from slavery - including his wife Elizabeth and children (abolished by the 1799 law of In New York, she was transformed into a state of a servant and was not eligible for complete liberation until 1827). Later, most of his income was devoted to abolition of slaves. In 1831, Jennings became the assistant secretary for the first Annual Conference for Colored People in Philadelphia.

Legal issue

Luckily for Jennings, he received a patent at the right time. US patent law from 1793 to 1836, both slaves and ordinary citizens can file for their invention. But in 1857, a slave owner named Oscar Stuart signed up for "a double beard", which was an invention of a slave named Ned. Stuart said that "it is the slave owner who inherits the fruits of the slave, both labor and intellect".

In 1858, the US patent office changed its rules in response to the Supreme Court's case concerning Stuart's patent, Oscar Stuart v. Ned. The court ruled that Stuart was not a citizen and could not be granted a patent. But surprisingly, in 1861, the United States passed a law that granted slavery, and in 1870 passed a patent law that granted all American men including blacks the right to their inventions.
