Of all the Wikipedia pages out there - just 19 percent are about women.
It was something that Dr Jess Wade stumbled onto, after she went searching for more information about Kim Cobb, an American climatologist she'd just met, and found she had no profile on the platform.
It inspired her to pen her first Wikipedia entry - she's now written close to 1800 profiles of female scientists.
Jess is a physicist herself, based at Imperial College London.
Her work building the knowledge about women's achievements in science has earned her a British Empire Medal.
