Franklin, Benjamin (1706 - 1790)

Benjamin Franklin was one of the founding fathers of the United States of America. While not considered a mathematician, he did construct some interesting magic squares. He constructed 8x8 and even an 16x16 magic squuare. Franklin magic squares are known to have constant row and column sums and though they may lack the two diagonal sums, they do possess other magical sums, including the bent rows.
