International Women in Engineering Day

This Friday, June 23rd, is International Women in Engineering Day, a day that “focuses attention on the amazing careers in engineering and technical roles for girls, and allows us to celebrate the achievements of our outstanding women engineers.”

To celebrate, we’ve compiled a timeline of powerful and influential female engineers and designers who dismantled and continue to dismantle the harmful assumption that engineering is an industry reserved for men.
