A black and white photo of Katherine Johnson sitting at her desk. She is wearing glasses and white or light dress with short sleeves and a collar. Johnson is looking to the right of the photographer. An analog adding machine sits on the desk in front of her, along with several papers and a translucent globe with multiple axes used for orbital calculations. She is holding a pen or pencil in her right hand, and wearing a bracelet or watch on her left wrist.

Mathematician Katherine Johnson was born #OTD in 1918.
Her orbital mechanics computations played a vital role in many early NASA missions. Astronaut John Glenn trusted her calculations more than those of his onboard flight computer.
