Innovation & the Space Station

Space exploration would not be possible without incredible feats of innovation, science and technology. In fact, we could have never reached the moon without the creativity and imagination of Robert H. Goddard, who invented the first liquid propellant and multistage rocket engines in 1913 and 1914. After many more iterations and innovations, Goddard successfully flew the world’s first liquid propellant rocket in Auburn, Massachusetts in 1926, leaving an indelible mark on space exploration.

Necessity is the Mother of Invention

Inventor and trailblazing Civil Rights activist, Marjorie Stewart Joyner was among the first African American women to receive a patent.

Marjorie Joyner was the first African American to graduate from the A. B. Moler Beauty School, where she met hair care mogul Madame C. J. Walker. While teaching for Walker Beauty Schools, Joyner patented the permanent wave machine.

Joyner taught for more than 50 years and was devoted to her students. She founded the Alpha Chi Omega Sorority and Fraternity for beauty culture students in 1945 and, a year later, the United Beauty School Owners and Teachers Association. She later helped draft the first cosmetology laws for the State of Illinois and was a founding member of the National Council of Negro Women.
