Peter Stevens, who lives in Quincy, Massachusetts, writes frequently on historical themes. Marian Eide is a graduate student in the Comparative Literature and Critical Theory Program at the University of Pennsylvania. We would like to thank Dr. Stephen Lazoritz for his contributions to the research of this article. Lazoritz, a pediatrician specializing in child-abuse cases, first became interested in Mary Ellen’s history when, preparing for a lecture on child abuse, he read “The Great Meddler,” Gerald Carson’s profile of Henry Bergh in the December 1967 issue of American Heritage. Lazoritz was fascinated by the child and traced her history through a trail of documents and newspaper articles. In the story of Mary Ellen’s childhood he found the roots of a movement to prevent child abuse in which he is very much involved today. Lazoritz’s youngest daughter was born during his pursuit of the case. Her name is Mary Ellen. Thanks, too, to the New York Society for the Prevention of Cruelty to Children, whose archives contain full documentation of the Mary Ellen case.
