Oscar Ratti, now a commercial illustrator, received his degree in classical studies and law from the University of Naples where he was intercollegiate Greek-Roman wrestling champion and a member of the championship judo team. He later came to the United States and began to study aikido with Yasuo Ohara, one of the first instructors to teach in New York. In addition to being co-author of the book, Mr. Ratti provided all the excellent drawings that appear in this volume.
Mr. Ratti and Ms. Westbrook have also taught aikido in New York, working with youth groups at Centers associated with the Y.M.C.A.
