Excerpt:
"I was asked by a colleague to give a presentation on a local author as part of the 300th anniversary celebration for Windam County in Connecticut, where I live. I soon found that the area author who seemed to have the greatest readership was Gertrude Chandler Warner, who had written nineteen volumes of the 'Boxcar Children' mystery series for children. Even though I don't think it was quite what the university expected, I gave my paper on Warner, and it seemed to be thoroughly enjoyed by all the colloquium participants. One participant, the president of Putnam's Aspinock Historical Society, asked me to give a talk on Warner at his group's spring meeting the following year. That meeting was a lot of fun; local residents and former Warner students came, bringing anecdotes and mementos, and we videotaped the evening. Then I put my Warner materials away as I went on with my teaching and other writing projects. Many months later, on a cold fall afternoon, I received a call from a college administrator in Florida, whom I did not know. She said that she had grown up in Putnam and had Miss Warner as her teacher. Her mother had sent her the videotape of the Putnam evening for her birthday. Coincidentally, at a recent booksellers' meeting, a representative of the Albert Whitman Company, Warner's publisher, had mentioned to her that they were looking for someone to write Warner's biography. She was sure I was the one to do it! So I prepared a manuscript and gave it a trial-run on the second-graders in our local elementary school..."
