Which famous inventor wrote his notes in mirror writing?

The famous inventor who wrote his notes in mirror writing was Leonardo da Vinci.

He wrote from right to left, as if looking at his writing in a mirror. While the reason for this is still debated, some theories suggest:

* Left-handedness: Da Vinci was left-handed, and writing in mirror script allowed him to avoid smudging the ink with his hand.

* Privacy: It kept his notes private, as only someone familiar with mirror writing could read them.

* Artistic Style: Da Vinci was a visual artist and may have enjoyed the artistic challenge of writing in this way.

Regardless of the reason, it's an intriguing aspect of his legacy.
