Leonhard Euler

Little-Known Facts

Euler lost most of his sight late in life yet continued producing mathematics at an astonishing pace, dictating to assistants.
His collected works fill dozens of large volumes and are still being edited centuries later.

Did blindness end Euler's career?

No. Even after becoming nearly blind, Euler produced roughly half of his total output, relying on his prodigious memory and mental calculation.
