What US President could write Greek and Latin with the right hand and the left hand?
President James Garfield, who was our first left-handed
president*, could write with both hands at the same time in two
different languages. In one hand he would write Ancient Greek, and
in the other he would write Latin!
*President Garfield actually may have been ambidextrous. He may
have been either, that part will have to be corrected by another
contributor.
