I had read in one book that Jefferson was a Mason, but this site I found
stated that this was unclear:
"1801-1809 Thomas Jefferson, 3rd. President of the United States (DR)
Confirmed Illuminati. Jefferson was a member of the Lodge of the Nine
Muses in Paris and the Beenan Order (Order of the Bees) known outside
Bavaria as the Illuminati. Vice President, Aaron Burr (DR), 1801-1805.
Confirmed Mason. "
