Who Invented the Spark Plug?
Some historians have reported that Edmond Berger who invented an early spark plug (sometimes in British English called the sparking plug) on February 2, 1839. However, Edmond Berger did not patent his invention.
And since spark plugs are used in internal combustion engines and in 1839 these engines were in the early days of experimentation. Therefore, Edmund Berger's spark plug, if it did exist, would have had to have been very experimental in nature as well or perhaps the date was a mistake.
What Is a Spark Plug?
According to Britannica, a spark plug or sparking plug is "a device that fits into the cylinder head of an internal-combustion engine and carries two electrodes separated by an air gap across which current from a high-tension ignition system discharges to form a spark for igniting the fuel."
More specifically, a spark plug has a metal threaded shell that's electrically isolated from a central electrode by a p

Transportation history cannot be told without the influence of Black history. Many of the devices we use and the inventions we travel with were made or impacted by influential Black leaders and trailblazers. Our world today would look a lot different without the work of these prominent Black figures, so let’s acknowledge these works not just during Black history month but as part of transportation history.
Andrew Jackson Beard — Rotary Steam Engine & Railroad Coupler
Andrew Jackson Beard (1849–1921) was born into slavery in Jefferson County, Alabama. Emancipated at age fifteen, he then became a farmer and was in charge of a flour mill. Although Beard did not have any formal educational training, he could not stop his brain from tinkering and thinking up new inventions. In 1892, he patented a new type of steam-driven rotary engine. During this time, the U.S. was looking for cheaper, alternative power sources to help drive industrialization other than electricity. Bear
