Jefferson

From Wikipedia – When President John F. Kennedy welcomed forty-nine Nobel Prize winners to the White House in 1962 he said, "I think this is the most extraordinary collection of talent and of human knowledge that has ever been gathered together at the White House – with the possible exception of when Thomas Jefferson dined alone."

The best reference I found was from a Rembrandt painting. The painting was awesome. Let's put how long it took us. 35 minutes.
