Leonardo da Vinci

15 April 1452 – 2 May 1519

Inventor, Painter, Designer, Musician -"Renaissance Man"

Leonardo da Vinci was an inventor, painter, and sculptor whose broad interests also included architecture, science, music, mathematics, engineering, literature, anatomy, geology, astronomy, botany, writing, history, and cartography.

Art historian Helen Gardner wrote that the scope and depth of his interests were without precedent in recorded history, and “his mind and personality seem to us superhuman”.

One remarkable indication that Leonardo was dyslexic is in his handwriting. Leonardo was constantly sketching out his ideas for inventions. Most of the time, he wrote his notes in reverse, mirror image:

Although unusual, this is a trait sometimes shared by other left-handed dyslexic adults. Most of the time, dyslexic writers are not even consciously aware that they are writing this way; it is simply an easier and more natural way for them to write.

Leonardo’s spelling is also considered erratic and quite strange. He also started many more projects then he ever finished – a characteristic now often associated with attention deficit disorder (ADHD).

However, when it came to his drawing and artwork, Leonardo’s work is detailed and precise.

When he drew his flying machine, he wrote (backwards, of course): “A small model can be made of paper with a spring like metal shaft that after having been released, after having been twisted, causes the screw to spin up into the air.”

 

His extraordinary art work and inventive genius are proof that he truly possessed the gift of dyslexia.
