Featuring twenty one Old Master artworks spanning the 16th to 19th centuries, the collection highlights the underrecognized achievements of female artists during a period in which just being a female artist was an achievement in itself.

The country’s first female doctor, who started a hospital for women and children in downtown Manhattan in the 19th century, will be commemorated Monday by Greenwich Village residents. Elizabeth Blackwell attended a medical school in upstate New York, becoming the first woman in the United States to earn a medical degree in 1849. She and her sister Emily, who was the third woman in the country to become a doctor, then founded the first women’s hospital, New York Infirmary for Women and Children, on Bleecker and Crosby streets in 1857.

As part of a worldwide campaign, coinciding with Women’s History Month, institutions across the city are hosting a Wikipedia edit-a-thon to wipe out erroneous information and add new facts and pages about women and femmes (those who identify as women) who have made an impact on history. Hundreds of artists, activists, preservationists, movers and shakers and numerous terms have not been given much attention or written about at all on Wikipedia, according to the group organizing the event, Art + Feminism.
