Although Henry Blair is the first inventor to be identified as black by the U.S. Patent Office, he is not the first African American to be awarded a U.S. patent. Most historians agree that Thomas L. Jennings is the first African American patent holder in the United States. Jennings invented a way to dry-clean clothes in 1821. Judy W. Reed, of Washington, D.C., was the first African American woman to receive a patent. Reed's invention, patent number 305,474, granted September 23, 1884, is for a dough kneader and roller.

A patent is a government grant to an inventor for an invention. George Washington signed the first patent law on April 10, 1790. The law gave patent holders the sole right to make and sell their invention for fourteen years. It prevents other people from copying their invention and making money off it during that time. The Patent Act encourages progress in science by allowing patent holders the right to make a living from their own creativity.
To receive a patent, an invention must be new and contribute something useful. A patent can't be granted to something that has already been invented, but a patent can be granted to improve an already existing invention. Patents can be granted to machines, products, devices, and processes. Chemical compounds, food, drugs, and the processes to make these things can also be patented.
Before the Civil War (1861–1865), slavery was legal in the United States. Slaves were considered property and couldn't apply for patents. This didn't stop slaves from creating new inventions. Onesimus, a Massachusetts slave owned by Puritan leader Cotton Mather, is credited with making a remedy for smallpox that was introduced in 1721. Another Massachusetts slave, Ebar, invented a broom made from broomcorn around 1800. Papan's treatment of skin and sexually transmitted diseases (STDs) was so effective the Virginia state legislature freed him from slavery to practice medicine.
The following three men are notable African American inventors of the 18th century. All three men were born free; they were not slaves. There may have been many more African Americans, slave and free, who came up with inventions, but their stories have been lost to history.
Benjamin Banneker (1731–1806) was a self-taught mathematician and surveyor. When he was 21, Banneker was shown a pocket watch. He was so fascinated by the watch that its owner gave it to Banneker. He took it apart and put it back together several times before deciding to build his own timepiece. A year later, Banneker invented a clock out of wood that struck a gong on the hour and kept time to the second. Banneker's wooden clock kept time for more than 40 years.
In 1792, Banneker completed the first Banneker's Almanac. Almanacs were important books in the 18th century because they told exactly when the sun came up in the morning and set at night. Almanacs also listed tide tables, dates of lunar and solar eclipses, holidays, and phases of the moon. Banneker's Almanac was commonly used by farmers and other residents of Pennsylvania, Delaware, Maryland, and Virginia during the 18th and 19th centuries.
Banneker gave a first edition of his almanac to Thomas Jefferson. Banneker called on Jefferson to give black men and women equal rights, and to fight against prejudice that was "so prevalent in the world against those of my complexion . . . a race of beings, who have long labored under the abuse and censure of the world." Jefferson replied to Banneker, writing, "nature has given to our black brethren talents equal to those of other colors of man." Slavery would be abolished 59 years after Banneker's death.
James Forten (1766–1842) was born in Philadelphia, Pennsylvania, and lived there most of his life. He served in the U.S. Navy during the Revolutionary War. Captured and imprisoned by the British, Forten was offered his freedom if he agreed to live in England. Forten replied, "I am here a prisoner for the liberties of my country. I never, never shall prove a traitor to her interests!"
After the war, Forten was apprenticed to a sailmaker. He quickly learned the trade and developed a patent for a device to handle ship sails, which made him a wealthy man. Forten used his money to advocate for women’s rights and the abolition of slavery.
George Peake (1722–1827) also fought in the Revolutionary War. He was the first African American to be part of the settlement that eventually became Cleveland, Ohio. At this time, Ohio was a largely unsettled frontier in the western part of the United States.
Peake invented a hand mill for grinding corn. His hand mill was made of two round stones approximately nineteen inches wide. Peake's invention was easier to use than the traditional mortar and pestle, and ground the corn more smoothly. Although Peake didn't patent his invention, he received credit for it in the November 8, 1858, issue of the newspaper Cleveland Leader.
