Female scientists’ pages keep disappearing from Wikipedia – what’s going on?

A deletion battle over a black female chemist’s biography has put Wikipedia’s gender gap in the spotlight. There are far fewer biographies of women on Wikipedia, compared with men, and the ratio of female to male scientists is even worse. There is no simple answer to why this is happening, however, with societal pressures, the demographics of Wikipedia’s editors and the encyclopaedia’s bureaucracy all playing a part.
