He taught judo at Queens College and at various YMCA clubs in the New York City area. He served as vice-chairman of the National AAU Judo Committee and was awarded a second-degree black belt by the Kodokan in Tokyo. Yerkow published six books on judo, including the three-volume Modern Judo series (Basic, Advanced, and 40 Gokyo Techniques), Sport Judo, Judo Katas, and Official Judo. Emilio Bruno described him in a 1972 letter as \"one of our very excellent judo pioneers\" who \"published the first judo book in the U.S. during World War II.\""@en ;

Emilio Bruno (1972) describes him as \"one of our very excellent judo pioneers\" who \"published the first judo book in the U.S. during World War II\" and \"did much to throw proper light on judo as a sport and method of self defense in the U.S.\" Bruno also notes that \"he did not receive the credit he deserved because the skills he demonstrated in his book didn't come up to the perfection expected by old, critical Black-Belters of the early days.\" The cover of Modern Judo states he was attracted to judo \"more than twenty years ago\" (suggesting he began around the late 1920s). No death date has been identified." .
