Heise

Ryan Heise proposed Tripod in 2002. Him having used Petrus, and creating the 1x2x2 concept from this method, was likely the start of the Heise method.

Ryan Heise experimented with non-matching blocks. This would lead to the non-matching 1x2x2s aspect of the Heise method.

The original version of the method was proposed in July, 2003.
