Museum education and progressive education both arose at the same historical period, approximately a century ago, and share not only a common history but also common features. Both emphasize pedagogy based on experience, interaction with objects, and inquiry. They also share a social vision of serving the entire society, including underserved audiences. The work of Anna Billings Gallup at The Brooklyn Children's Museum and Louise Connolly at the Newark Museum, exemplary museum educators during the early decades of the 20th century, illustrate the pedagogic and social aims of museum education in the progressive tradition. Their accomplishments can inspire us today. (Contains 4 figures and 22 notes.)
