Abraham Lincoln. Before he became president, he was interested in engineering. He wondered if there were a way to invent something that might keep ships from running aground, and he came up with an idea for inventing such a device. He received Patent 6469 on May 22, 1849. It was called "Buoying Vessels Over Shoals,"and although the actual invention never seems to have been built, he is the first (and only) president to hold such a patent.

What did President Lincoln invent?
On May 22, 1849, Abraham Lincoln received Patent No. 6469 for a device to lift boats over shoals. Lincoln's idea was to allow larger ships with deep hull to reach smaller towns in shallow areas of rivers.

Lincoln is the only US president to be awarded a patent.
