Day 7 Thomas Stewart – 28 days of Black History in Technology

Thomas Stewart patented a new type of mop, but that’s not why he is listed as Day 7 Black History in Technology.  He is listed because he co-patented an improved station and street indicator in 1883. It was used with railways and street cars to signal what road or street the vehicles were crossing.

Their indicator would automatically activate a signal by means of a lever on the side of the track.

While this fact might be short, his contribution along with William Edward Johnson, has saved hundreds, if not thousands of lives.


Day 6 Cordell Reed – 28 days of Black History in Technology

Cordell Reed born in 1938 was in charge of nuclear licensing and environmental activities for Commonwealth Edison Company of Chicago.  Reed started with the company in 1960, starting as an engineer assigned to the design, construction, and operation of coal-fired generating stations.

In 1967 he transferred to their Nuclear division, his task was developing more efficient and productive power plants.  The work he did during that time lead him to a promotion in 1975 as he was appointed manager of the nuclear engineering department, where he headed a group of 75 engineers who were responsible for the engineering design of all nuclear projects.

During Reeds work Commonwealth became the Nations’ leading nuclear utility;  Reed is a native of Chicago, and holds a masters degree in engineering from the University of Illinois.

Here is my salute to Mr. Reed for leading the way in the improvements, and literally writing the book on Nuclear Policy.


Day 3 Marie Brown – 28 days of Black History in Technology

Do you have a home security system? Better yet do you have a home video suvallance system?  While the home security system is a very common item in most homes today, Marie Brown managed to do something no one had done before.

In 1966 she filed a patent for a closed-circuit television security system.  The patent was way a head of it’s time, it included 4 peep holes in the front door of a home.  A camera could slide up and down to look out each hole and that would be wirelessly beamed to a televison so the person inside could know who was at the door.  The person looking at the video could then unlatch the door by remote control.

Marie Van Brittan Brown was born October 30, 1922, she died on February 2, 1999 at the age of 76.  Mrs. Brown along with her husband Albert Brown also filed for other patents.

Patent #3,482,037 Filed August 1, 1966 Issued December 1969.

Below is the PDF of the patent with drawings, and explanation of this invention, please take a look at the drawings they are amazing.

28 days of Black History in Technology

Black History Month 2011February is here and that means “Black History Month” most of us remember these days from our childhood where schools would try and give some information about the contributions that African Americans have given to history. Keeping with that theme I decided to give the world a little bit of Black History myself. I decided to blog about  28 individuals over 28 days that have contributed to Black History with a Technology core.

If you read this blog then you know how often I post… almost once every two months, and if you know me then you can see how this could be a disaster or a compelling success. I want this to be a success, and I’m going to make sure I keep going with valid information about African Americans that have contributed to Black History in some Technological way.  If you want to thank someone for giving me the bug to do this, it’s my good friend Wayne Sutton his blog is here and he created the site “28 day of diversity“.

How ever big or small I want to take a moment to give light to some old and some new individuals that are making waves in Technology or have made waves. A word of caution I’m not here to debate all that these people have done in the world right or wrong, it’s a light that I want to use to help someone or give someone information they may not have known.

So pull up a chair and take a moment to read some of these post I will be bringing to you each and every day. By all means please send comments good or bad so that we can start a dialog about these people here on TBTR.

I hope you enjoy this “28 days of Black History in Technology”
