Who invented the jigsaw puzzle in 1767?

There is no record of the jigsaw puzzle being invented in 1767. The invention of the jigsaw puzzle is often attributed to John Spilsbury, an English mapmaker and engraver, around 1760.

Spilsbury created the first jigsaw puzzles by gluing maps onto wood and then cutting them into irregularly shaped pieces. These puzzles were educational tools used for teaching geography.
