My Aunt Jennie was editor of The Horn Book, which is still being published but I think was more prestigious back in the 1950s because it was the only magazine of its type, reporting on children's literature. She was a children's author herself, and her first book, The Golden Name Day, was one of the Newbery Medal nominees when it came out. As editor of the Horn Book she was automatically on the decision committee, but took herself off because of the rather obvious conflict of interest. It was runner up to Carry On, Mr. Bowditch. The illustrations to Jennie's books were by Garth Williams, so they have a similarity of appearance to the "Little House on the Prairie" series.
Her first issue as editor was Jan-Feb 1951, and included her reviews of new books. Included in the batch was The Lion, The Witch and the Wardrobe, which was published in October of 1950. I conclude that she was the first American to review the book, as she was likely also the first to review The Voyage of the Dawn Treader near.y two years later. We have that first issue, which she sent to her cousin Selma, my beloved Aunt Sal. I discovered it while going through all the family artifacts to display to the children and grandchildren before we weed through it all. It will now go to Houston to live with one of my sons.
