Lewis Latimer is considered one of the 10 most important Black inventors of all time, not only for the sheer number of inventions created and patents secured but also for the magnitude of importance for his most famous discovery. Latimer was born on September 4, 1848 in Chelsea, Massachusetts. His parents were George and Rebecca Latimer, both runaway slaves who migrated to Massachusetts in 1842 from Virginia. George Latimer was captured by his slave owner, who was determined to take him back to Virginia. His situation gained great notoriety, even reaching the Massachusetts Supreme Court. Eventually George was purchased by abolition supporters who set him free.

Lewis served in the United States Navy for the Union during the Civil War, assigned to the U.S.S. Massasoit gunboat and received an honorable discharge on July 3, 1865. After his discharge he sought employment throughout Boston, Massachusetts and eventually gained a position as an office boy with a patent law firm, Crosby and Gould earning $3.00 each week. After observing Latimer’s ability to sketch patent drawings, he was eventually promoted to the position of head draftsman earning $20.00 a week. In addition to his newfound success, Latimer found additional happiness when he married Mary Wilson in November of 1873.

In 1874, along with W.C. Brown, Latimer co-invented an improved of a train water closet, a bathroom compartment for railroad trains. Two years later, Latimer would play a part in one of the world’s most important inventions.

In 1876, Latimer was sought out as a draftsman by a teacher for deaf children. The teacher had created a device and wanted Lewis to draft the drawing necessary for a patent application. The teacher was Alexander Graham Bell and the device was the telephone. Working late into the night, Latimer worked hard to finish the patent application, which was submitted on February 14, 1876, just hours before another application was submitted
