Congrats Steve! It is indeed magician Carl Herrmann. " He came from the magical Herrmann family of Hanover, Germany. One of his stops while on tour in America in 1861 was the White House where he performed in the East Room for Lincoln and a group of cabinet members. When he tried to get Lincoln to shuffle a deck of cards, Lincoln handed them to Simon Cameron, his secretary of war, saying 'This gentleman shuffles the cards for me at present.'
