>also wasn't missed by Dr. Krebs, an award winning biochemist,

From http://www.quackwatch.org/01QuackeryRelatedTopics/Cancer/laetrile.html

"Ernst T. Krebs, Jr. -- Laetrile's "father" -- has often been referred to as
"Dr. Krebs" although he has no accredited doctoral degree. He attended
Hahnemann Medical College in Philadelphia from 1938 to 1941, but was
expelled after repeating his freshman year and failing his sophomore year
[3]. After taking courses in five different colleges and achieving low or
failing grades in his science courses, he finally received a bachelor of
arts degree from the University of Illinois in 1942 [3]. In 1973, after
giving a 1-hour lecture on Laetrile, he obtained a "Doctor of Science"
degree from American Christian College, a small, now-defunct Bible college
in Tulsa, Oklahoma. The school, founded by evangelist Billy James Hargis,
had no science department and lacked authority from Oklahoma to grant any
doctoral degrees."

I'm afraid I do not think too much of him....
