Louis Latimer: Black Inventor and Thomas Edison Associate

Born the son of a freed slave, Lewis Howard Latimer (1848-1928) is an outstanding role model for young folks-how to overcome whatever odds against success and succeed. In his 80 years he was an inventor, patent expert, draftsman, engineer, author, poet, and musician.

During the Civil War he joined the U.S. Navy, serving aboard a side wheel gunboat, the U.S.S. Massasoit, until the war’s end in 1865. Returning home, he soon taught himself mechanical drawing, subsequently holding a job in this capacity, preparing formal drawings submitted to the U.S. Patent Office. He helped prepare the drawings for Alexander Graham Bell’s original telephone patent.

Later, in 1880, he would work for Hiram Maxim, a prolific inventor and contemporary of Bell and Edison, who like Edison was working on electric lighting. While with Maxim, Latimer patented a process for making carbon filaments for bulbs, and taught workers to make the filaments. This knowledge soon mushroomed into Latimer setting up and consulting in Maxim factories here and abroad.

In 1884, Latimer was named a draftsman-engineer in Edison’s New York operations; and in 1889 as an expert electrical engineer, wrote a highly regarded technical book of its time, “Incandescent Electric Lighting—A Practical Description of the Edison System”. In that same year, he penned a book of poetry, celebrating his life-long love of creative writing. Latimer also served as an expert witness for Edison, testifying on behalf of the great inventor in many court cases challenging Edison’s electrical system.

By 1892, Latimer was involved in consulting roles with General Electric, Westinghouse, and finally a prestigious New York engineering/patent law firm-eventually retiring from that firm in 1924 at the age of 75. While at the law firm, the “Edison Pioneers” was formed, a group dedicated to keeping alive the ideals and aims of Thomas Edison. Latimer was one of the original members.

Today, Latimer is considered one of the top ten black inventors, up there in stature with the great George Washington Carver who held many patents. Latimer was a great man, and patriot … a role model for all students … a man who never stopped learning and improving himself.

Edison-Einstein-Disney: Three of a Kind

BREAKING NEWS: Edison and Einstein appear in cameo shots in a trailer promotion for Disney’s new film, “Tomorrow Land”, a movie to premier soon in Japan. George Clooney stars in the movie. 

Edison-Einstein-Disney: Three of a Kind

When you hear these names your mind naturally associates them with people who changed the world. They tend to bring smiles to your heart and mind-three men who did some really cool things; and who shared some very interesting commonalities you can read about below.

  • All three had issues with formal schooling-experiencing problems with the emphasis on rote memory; and little room for other ways of learning. They
    may have all suffered from dyslexia, and related learning problems.
  • These great achievers valued hard work, creativity and imagination in their pursuits.
  • Persistence characterized their work, bringing forth ideas in spite of repeated failures; and learning through failure.
  • With an eye on the future, these innovators knew how valuable it was to be pushing the envelope of thought; and doing so in the service of humanity.
  • They all went beyond conventional problem solving– ”disruptors”, as we would say today.
  • Read and learned from a wide variety of fields and literature.
  • Kept advancing and refining their ideas.
  • Were playful, humorous, and even played practical jokes on friends/co-workers.

Consider some quotes from these gentle, giant, applicators:


“I never perfected an invention that I did not think about in terms of the service it might give others… I find out what the world needs, then I proceed to invent …“

“To invent, you need a good imagination and a pile of junk.”

“Surprises and reverses can serve as an incentive for great accomplishment. There are no rules here, we’re just trying to accomplish something”




“Try to become not a man of success, but try rather to become a man of value.”

“Imagination is more important than knowledge. Knowledge is limited. Imagination encircles the world.”

“The aim [of education] must be the training of independently acting and thinking individuals who, however, see in the service to the community their highest life problem.”




“If you can dream it, you can do it.” [Walt once quipped, the whole Disney adventure started with a mouse and a dream.]

“It’s kind of fun to do the impossible.”

“The way to get started is to quit talking and begin doing.”
