Lincoln’s (and Darwin’s) birthday rolls around again next week. What do we know about our 16th president who was the subject of a great and a silly movie in the last year?
Some wag sent out this Tweet today.
Any visitor to Thomas Jefferson’s home at Monticello knows of Jefferson’s wide-ranging interests, and work in science and invention. I was rather surprised to discover the depth of George Washington’s inventive work, in a seminar sponsorred by the Bill of Rights Institute at Mount Vernon a few years ago.
Abraham Lincoln, too?
Lincoln lived along the Sangamon River, and he saw development of the river for commercial navigation to be a boon for his district’s economic growth. Unfortunately, the Sangamon is not deep; boats had difficult times navigating over the many logs and snags, and shallows.
So, Mr. Lincoln offered a technical solution, for which he was granted a patent in 1849. Details below, from Google Patents:

Drawing for Abraham Lincoln’s patent of a boat bouying apparatus.
Was Lincoln the only president to get a patent? Thomas Jefferson and George Washington worked hard at inventions. Jefferson shared Ben Franklin’s view that new inventions should be for the benefit of all; does that mean he didn’t seek patents? Washington’s inventions — including the 16-sided barn for threshing wheat — tended to be improvements on processes; I don’t know of any evidence he even thought of patenting any idea.
It’s possible that Lincoln was the only president so far to have held a patent.
Lincoln’s invention was never built, and that patent never used.
This is an encore post with additions.

There was an earlier patent office — in the British invasion of 1814, it was the only official building in Washington the British did not torch. Nor sure how the office operated prior to 1836, but the instruction to look after them is in the Constitution, and there was an office prior to 1836, prior to the death of Jefferson by at least a dozen years.
You raise some interesting issues to track down. Got more light to shed?

Since both Washington & Jefferson died well before the creation of the modern U.S. Patent Office in 1836, and only a small number of the preceding “x” Patents survived a fire later that year, it would be very hard to say whether either of them had been granted a patent. It would certainly not be impossible.
