On June 20, 2003 Ryan Heise first mentions that he developed the method.
On July 1 2003, the method is described.
The method is added to Ryan Heise's website around late April or early May 2006.
The website states that the method was created in December of 2002.
Dan Kroc mentions having created a similar method in 1984.
My guess is that this is Dan Kroc based on the mention of achieving a time of 30.68 seconds at a competition in Burnsville, Minnesota.
I knew about the Cube-A-Thon competitions and found the 30.68 time in Burnsville. The person that wrote the post says that they were 14, but the person that achieved the 30.68 time is listed as 16.
