Kempo / Kenpo
(A brief history in outline form)

--  Originated from basics in Kung Fu
--  Professor William Kwai-sun "Thunderbolt" Chow's father brought Kung Fu
      from Shanghai to Hawaii where he then taught William as a young man
--  Unhappy with just the Kung Fu, William later joined forces with James Mitose.
      They developed an "unbeatable" combination of empty-hand street defenses, but
      eventually split up.
--  Mitose called his version, Chinese Kempo
--  Chow called his version, Chinese Kara-Ho Kenpo and by 1945 Chow had his
      Kenpo refined.
--  Professor Chow died in 1987 at 74 years old.
--  The leadership was assumed by Sam Kuoha who had trained 22 years under
--  Kenpo was brought to the United States by Ed Parker, who first trained under
      Frank Chow and then under William himself.
--  In many circles Ed Parker is thought of as being the "Grandmaster" of Kenpo.
--  Kenpo requires 6 years to acquire Black-Belt.
--  The word "and" is not used in teaching or working Kenpo.  The "space" of "and"
      in a technique is wasted time in execution.

With reference to Sam Kuoha, he began his Kenpo training at the age of six.  They trained 8 to 10 hours a day, 6 days a week.  He had to "earn" a white belt!  They first tied their Gi's with a piece of rope.  It took 3 years to earn the white belt.  Their skill level at this time was equal to many Black-Belts in other systems.  In the beginning years, for the period of one year, he did only one kick and punch, day in and day out.

There is more information directly related to this, if you can find one, in BlackBelt Magazine, dated January 1989, starting on page 55.
