Clara Ingram Judson (May 4, 1879 – May 24, 1960) was an American writer who wrote over 70 children's books, primarily nonfiction including several biographies of American presidents. In 1960, she won the second Laura Ingalls Wilder Medal from the professional children's librarians, although she died before she could receive it. The award recognizes a living author or illustrator whose books, published in the United States, have made "a substantial and lasting contribution to literature for children". Source: Wikipedia (en)
