Commemorating President's Day

George Washington was an inventor and the only president to hold a trademark.

Thomas Jefferson invented, among other things, the swivel chair, a macaroni machine, the spherical sundial and the cipher wheel. He also is credited with introducing french fries to the United States!

Abraham Lincoln held a patent for "A Device for Buoying Vessels Over Shoals." He was the the only president to hold a patent.
"In 1858 Lincoln called the introduction of patent laws one of the three most important developments 'in the world's history.' The other two, he said, were the discovery of America and the perfection of printing."
