To combat bias on the free encyclopedia’s pages, two leaders of 500 Women Scientists Jess Wade (Imperial College London) and Maryam Zaringhalam (AAAS Science & Technology Policy Fellow) began hosting Wikipedia Edit-a-thons. In celebration of Ada Lovelace Day in October 2018, 500 Women Scientists chapters in Atlanta, Madrid, Montreal, Washington D.C. and Storrs hosted edit-a-thons over the course of two weeks, writing 69 new biographies and editing over 400.
