Google has marked International Women's Day 2017 with a slideshow featuring 13 female pioneers from across the globe who it says have "paved the way to where we are today."
Acknowledging that some of the women featured in the Doodle may not be household names, the internet search giant says each of them have "made a mark in her own way".
"They pursued a range of professions and passions and hailed from an array of backgrounds and countries. In fact, all of these women have been featured in individual Doodles in the past, but often only in their countries of origin. So today we're taking the opportunity to share their stories with everyone."
Google continues: "After all, that's part of the original spirit of International Women's Day: giving a voice to women who might not otherwise be heard.
"We hope you enjoy the journey through time and space to learn about these phenomenal women," the statement adds.
According to Google, it all started in 1908 in New York City when a group of women gathered to demand fair pay, better working conditions and the right to vote. In 1911, the first official International Women's Day rallies were held in Austria, Denmark, Germany and Switzerland.
