Google is marking International Women’s Day with its latest Doodle, which highlights the importance of role models in inspiring the next generation. While International Women’s Day is very much about looking to the future and what women are striving to achieve globally, it is worth looking back at those who laid the groundwork as pioneers for diversity. That job has been put in the hands of the latest Google Doodle, which turns back the clock to highlight 13 women who have made their mark in various fields, from astronomy and physics to sport and art. The Doodle slideshow illustrates a grandmother telling her granddaughter a bedtime story that features these important women. In fact, all of these women have been featured in individual Doodles in the past, but often only in their countries of origin.
