Celebrating International Women’s Day: Notable women in US history since 1900

As women around the world mark International Women's Day, the theme for this year's celebration is Each for Equal.

"We can actively choose to challenge stereotypes, fight bias, broaden perceptions, improve situations and celebrate women's achievements," the website for International Women's Day notes.

Sunday's Google Doodle also celebrated International Women's Day with a video on YouTube.
