Edna Dean Baker (1883-1956) was a pioneering educator who helped develop standards for early childhood education in the U.S. She served as president of the National College of Education (now National Louis University) from 1920 until 1949 and, with her sister Clara, founded the Baker Demonstration School there. The two were early proponents of kindergarten and preschool, where they developed their “learning by doing” approach. A nationally recognized author, Baker also served on numerous national panels and committees promoting new standards in child education and care.
