Day 18 Annie Easley – 28 days of Black History in Technology

Annie EasleyAnnie Easley was born April 23, 1933 she received her Bachelor of Science in Mathematics from Cleveland State University.  Ms. Easley worked for the National Aeronautics and Space Administration’s Lewis Research Center and it’s predecessor agency (NACA)

Ms. Easley developed and implemented computer code used in determining solar, wind, and energy projects for NASA.  Her energy assignments have included studies to determine the life use of storage batteries, such as those used in electric utility vehicles.

Her computer applications are used to identify energy conversion systems that offer the improvement over commercially available technologies.

Ms. Easley’s work with the Centaur project helped as technological foundations for the space shuttle launches and launches of communication, military and satellites.  Her work contributed to the 1997 flight of Saturn of the Cassini probe, which was launched by Centaur.


Day 17 Clarence L. Elder – 28 days of Black History in Technology

Clarence L. ElderClarence L. Elder was born in 1935 he graduated from Morgan State College. In 1967 he was awarded a patent for a monitoring and energy conservation control system.

That system reduced energy use in vacant homes and buildings.  This was very useful for hotels and school rooms.  The system used an electronic beam aimed across the building entrance, this beam could gauge the coming and going of traffic.

The system could reduce heat and light demand and boast energy saving up to 30 per cent.

Patent # 4,000,400 filed April 9, 1975, issued December 28, 1976.

Day 16 O.S. (Ozzie) Williams – 28 days of Black History in Technology

Ozzie Williams

Mr. Williams was born September 2, 1921, he blazed a path of first, being that he had a Bachelor of Science and Master of Science in Aeronautical Engineering he was hired by Republic Aviation, Inc. during World War II.  No less this was at a time when African American were still not encouraged to become engineers.

Within four years working at Republic Aviation he was promoted to Senior Aerodynamicist.  Later Williams joined Greer Hydraulics, Inc. he was the group project engineer.  This team that he lead helped develop the first airborne radar beacon, this was useful for locating crashed aircraft.

Thought this mans efforts we are assured that no matter what happens in the sky if something goest wrong, we should be able to find it, because someone cared enough to think about those who were lost in Aircraft accidents.


Day 15 Walter Sammons – 28 days of Black History in Technology

While I’m on a roll of people that are not really high lighted in Tech, I wanted to give light to an individual that could be considered the savor for a lot of African Americans.  Walter Sammons of Philadelphia filed for a patent April 9, 1920.

Walter Sammons - Improved Comb PatentThe patent (1,362,823)was for an improved comb that straightend hair, his invention is now known as the “Hot Comb”

BTW my sister is gonna kill me for saying this, but I remember her and mom over the stove on many a Saturday using Mr.Sammons invention, lol

Day 14 Sarah E. Goode – 28 days of Black History in Technology

While Ms. Goode’s invention has nothing to do with technology, I thought she needed mention here because I know alot of us didn’t know this.  Ms. Sarah E Goode is the first African American Woman to file a patent.

Goode applied for and was awarded a patent on July 14, 1885. (Patent #322,177, for a cabinet bed).  Her invention was a something that was needed because of space in the small homes of america.

While her invention took a piece of furniture and converted it to a full bed, like a Transformer it was not popularized until years later.   Thirty years later in 1916 the Murphy bed was created. It was concealed behind a closet door or wall, rather than inside a piece of furniture, such as the cabinet bed.

Today it is known as a “folding bed” or the “hide away bed”.
