The current Featured Exhibition is Women in Cartography: Celebrating 400 Years of Unsung Contributions to the Mapping World.

This exhibition recognizes and celebrates the long overlooked role of women in the world of mapping; bringing their stories, accomplishments, and most importantly their maps to light. Curated by Alice Hudson, former Chief of the Map Division at the New York Public Library, Women in Cartography showcases the works of better-known women cartographers such as Marie Tharp, who, in partnership with Bruce Heezen, created the first scientific map of the entire ocean floor, and, Agnes Sinclair Holbrook who created the Hull-House maps, statistical cartographic presentations of social data from the immigrant rich Near West Side neighborhoods of Chicago.

Join us in celebrating these remarkable women and their maps, dating from Coletta van den Keere’s engraved portrait of Jodocus Hondius ca. 1613 to Claire Kiedrowski’s modern GIS and LiDAR work for Kappa Mapping in Maine.
