Master Dennis W. Lockwood’s diverse experiences served as the foundation of his dynamic direction, keen judgment, and loyal devotion to his students, peers, instructors, the martial arts, and Isshin~Ryu. He entered the world on July 21, 1943, a native of Salisbury, Maryland. With over forty-five years of combined service to the United States of America and as a karate-ka, his services range from a cryptographer in the United States Air Force (USAF, 1961-1965), to a programmer analyst for the National Aeronautics and Space Administration (NASA, 1976-2005) and martial arts studies of Tang Soo Do to Isshin~Ryu.
Master Lockwood was reared in Laurel, Delaware, attended Prince George Community College, University of Maryland Eastern Shore, and ended his studies with a Masters in Electrical & Computer Engineering awarded by the University of Amherst, in Massachusetts. He married his wife, Katherine, in 1965 while stationed in Greece, and they have two daughters; Laura and Anna. Master Lockwood is extremely proud of his daughters and grandchildren. Anna followed in her fathers footsteps and secured the rank of San-Dan. She studied with her father from age ten and was promoted to Sho-Dan at twelve. Sensei Anna Lockwood was a ranked competitor from 1982-1986, and is a highly respected martial artist.
Master Lockwood embarked on his martial arts journey in 1964, when he entered a Tang Soo Do dojo while stationed in Greece. Upon completion of a year of study, he was promoted to the rank of 5th Gup, green obi. While assigned to NASA in Greenbelt, Maryland, Master Lockwood continued to study Tang Soo Do until he moved back to the Eastern Shore and initiated his study of Isshin~Ryu with Master Tom Lewis in Salisbury, Maryland, in 1972. Master Lockwood was promoted to Sho-Dan in 1974, and was promoted to Nana-Dan in 2005, by Masters Tom Lewis and Reese Rigby.
Master Lockwood passed away unexpectedly on April 18, 2011 a few days after learning that he was being inducted into the Isshinryu Hall of Fame. Master Lockwood shared his thorough and perceptive understanding of the principles and spirit of Isshin~Ryu. He was a Sensei of impeccable integrity and soundness of moral principles, with personal and professional characteristics chiseled in truthfulness and honesty. Master Lockwood will be truly missed.
