Phebe W. Sudlow was the first female superintendent of a public school system in the U.S., serving in that capacity for Davenport Community Schools from 1874 to 1878. This photo of Sudlow was published in “A History of Davenport’s Schools” by Mary A. Baker. A scan of it can be found online in a 2010 blog posted by the Davenport Public Library entitled “Equality through Education: Phebe W. Sudlow” at blogs.davenportlibrary.com.
