Has anyone ever heard of Edward Leedskalnin?

I searched the forum using his last name and nothing came up so I thought I would bring this up under the against the mainstream heading. This fellow was a Latvian immigrant with only a fourth grade education. He was barely over five feet tall and weighed between 100 and 120 pounds. He lived in the early to mid 1900's. What he accomplished was truly amazing. He built what he called Rock Gate park, now known as the Coral Castle. Using only primitive tools and always working alone in secrecy he managed to cut, shape and move over three million pounds of coral stone, some of the blocks weighing up to 30 tons each I believe. He claimed he knew the secrets of how the pyramids were built and in his own unconventional way tried to explain some of these insights in several pamphlets. The Coral Castle has been featured on many television shows such as "In search of", "That's incredible" and such shows. Because he lacked the technical jargon of that time's scientific study his words seem rather mysterious and hard to follow, but there seems to be little doubt that this man had some usable knowledge at his disposal. There is a website which offers some of the details of his musings which I found quite interesting and would like to hear from you guys to see what you think.
