Black inventors who made our lives better

Posted On Feb 23, 2021, 09:55 AM by Victoria McGiffin

Imagine you are driving, approaching a busy intersection. The light is green and abruptly turns red.

Crime rates are spiking in your neighborhood. You are home alone and someone is knocking at your door but you have no way of knowing who is there.

You are at your local grocery store, crossing items off your list, except there are only dry goods. The chilled section has disappeared. Could you still make your favorite meal?

You are working from home on a screen with no color, no flexibility in movement, and everything you are doing is taking hours to load.

You got a new job at a train station and you need to let train #1 know that train #2 is heading its way. Your line of communication is out of reach; what do you do now?

Imagine that you would like to give blood to help save lives. There is no effective way to preserve your blood. What good will this be?

Thanks to the genius of Black inventors, the scenarios above are problems already solved.

Black history surrounds us. It is present in our every day lives in ways that many of us overlook and under-appreciate. In February, we pause to observe the significance of Black history.
