You're pretty close.  It is cited in Bartlett's Familiar Quotations as

"I think this is the most extraordinary collection of talent, of
human knowledge, that has ever been gathered together at the White
House, with the possible exception of when Thomas Jefferson dined
alone." J.F.Kennedy (Address to Nobel Prizewinners, 4/62)
