OURstory: Lewis Latimer (1848-1928)


Lewis Howard Latimer was born on this date in 1848. He was an African American inventor and innovator in the electric lighting industry. [SOURCE]

As a boy Latimer worked in his father’s barbershop in Chelsea, Massachusetts. He joined the Union Navy during the Civil War and after an honorable discharge in 1865 he found work with a firm of patent lawyers. Although Latimer was hired as an office boy, he cultivated drafting skills in his spare time until he was qualified for blueprint work. Latimer brainstormed his own work, patenting in 1874 a "pivot bottom" for water closets on trains. His high-caliber draftsmanship impressed Alexander Graham Bell, whose 1876 telephone blueprints were drawn up by Latimer.

In 1880 Latimer went to work for the inventor Hiram Maxim, who ran the United States Electric Lighting Company in Bridgeport, Connecticut and was one of Thomas Edison's prime competitors in the institutionalization of electric light. Under Maxim, Latimer supervised the installation of electric light in New York, Philadelphia, London, and Montreal. He also developed other inventions of his own, co-patenting an electric lamp with Joseph V. Nichols in 1881, and, most important, refining light-bulb technology in 1882. In 1884 he was invited to work for Maxim's arch rival, Thomas Alva Edison, in New York.

An expert electrical engineer, Latimer's work for Edison was critical for the following reasons: his thorough knowledge of electric lighting and power guided Edison through the process of filing patent forms properly at the U. S. Patent Office, protecting the company from infringements of his inventions; Latimer was also in charge of the company library, collecting information from around the world, translating data in French and German to protect the company from European challenges. He became Edison's patent investigator and expert witness in cases against persons trying to benefit from Edison's inventions without legal permission.

Edison encouraged Latimer to write the book, Incandescent Electric Lighting: A Practical Description of the Edison System. Published in 1890, it was extremely popular as it explained how an incandescent lamp produces light in an easy-to-understand manner.

On February 11, 1918, Latimer became one of the 28 charter members of the Edison Pioneers, the only African American in this prestigious, highly selective group. [photo: Latimer is standing left; Edison is the one with the cane]

After leaving Edison, Latimer worked for a patent consultant firm until 1922 when failing eyesight caused an end to his career. His health began to fail following the death of his beloved wife Mary Wilson Latimer in 1924. To cheer and encourage him to carry on, his children, two daughters, had a book of his poems printed in 1925 in honor of his 77th birthday.

The poems are beautifully sensitive, and complement Latimer's designation as a "Renaissance Man" who painted, played the flute, wrote poetry and plays. Lewis Howard Latimer settled in Flushing, New York and lived there until his death in 1928. He was an active member of the local community, teaching English and drafting to immigrants at the Henry Street Settlement in 1906. In 1968, Latimer was posthumously honored by the borough of Brooklyn when a public school was named after him.

It is important that we tell OURstory ... we cannot rely on his-story!

OURstory: Jan Matzeliger (1852-1887)

I agree with President Obama ... Kanye West is a 'jackass'. However, he seems to be a cultural icon for African American youth. Perhaps it is time for us to get busy providing some alternative icons for our youth. We have large numbers of Black and Brown students with little or not preparation in science, technology, engineering or mathematics (STEM) subjects. Without STEM background in the future, these students may find themselves with no employment opportunities.

Jan Ernst Matzeliger realized as much. Did you know that Jan Matzeliger was born on this date in 1852. He used STEM knowledge to create a shoe-lasting machine that mechanically shaped the upper portions of shoes.

Matzeliger was born on September 15, 1852 in Suriname (South America), the child of a biracial marriage. His father was a white engineer from Holland and his mother was a Black woman in the Dutch colony. By his third birthday Matzeliger was sent to live with his father’s sister. By the time he turned 10 years old, Matzeliger became a worker in the machine shop that his father owned. It was at this time that he quickly became aware of his talent for working with machinery.

Although he was skilled in this area, Matzeliger did not initially pursue a career in engineering or inventing. In 1871 at the age of 19 he left Surinam and worked as a sailor for two years. By 1873 he settled in Philadelphia where he worked in a variety of trades.

In 1876 he moved to Lynn, Massachusetts. Matzeliger arrived in Lynn barely able to speak English. Nonetheless he began working in a shoe factory. Despite his language difficulties, Matzeliger began working on various innovations that would improve shoe manufacturing productivity. Working alone and at night for six months, he produced a model in wood and on March 20, 1883, received a patent. The patent number is 459,899.

His patent was subsequently bought by Sydney W. Winslow, who established the United Shoe Machine Company. The continued success of this business brought about a 50% reduction in the price of shoes across the nation, doubled wages, and improved working conditions for millions of people dependent on the shoe industry for their livelihood. Winslow’s corporation made $50 million in the next dozen years and put Lynn, MA on the map as the shoe capital of the world.

Matzeliger’s work habits and his neglect of his health, however, soon took a toll. In the summer of 1887, he caught a cold then developed tuberculosis. Jan Matzeliger died on August 24 of that year in his mid-30s, long before he had the chance to realize a share of the enormous profit derived from his invention.

Matzeliger is not a household name but it should be. He was honored on a 29 cent first class U.S. postage stamp in 1991.

I hope that he included in the 2010 history portion of the BDPA high school computer competition! Jan Matzeliger should be discussed with our young people ... not Kanye West.
