There are various claims that L. Ron Hubbard (the creator of Scientology) had degrees and doctorates.
What formal education and qualifications did he have?
The recent New Yorker article about Paul Haggis and Scientology spends some time talking about how the Church has exaggerated Hubbard's achievements over the years. They made efforts to obtain original source documents that they found conflicted with what the Church has said:
The church document indicates, falsely, that Hubbard completed four years of college, obtaining a degree in civil engineering. The official document correctly notes two years of college and no degree.
They even posted all the documentation online so anyone can view them.
On a related note, there's a very interesting piece on NPR's site about the fact checking that New Yorker did for that article. Because of the Church's well-known litigiousness, it was extensive. The most interesting quote out of that article is about some discrepancies in Hubbard's war record, which also seems to have been embellished by the church.
"In one very interesting moment, Davis said, 'Of course, if it's true that Mr. Hubbard was never injured during the war, then he never did heal himself using Dianetics principles, then Dianetics is based on a lie, and then Scientology is based on a lie. The truth is that Mr. Hubbard was a war hero.' And the way he phrased that, that everything depended on whether Hubbard had sustained these injuries and healed himself was like a wager on the table."
