"Lovelace's potential was perhaps never fully realised...
..., as she died in 1852 at the tender age of 36."
A mathematician is over the hill at that age anyway.* Take your man Galois, did all sorts of cool stuff, including the maths which underlies the error correction on DVDs and undersea fibres. Dead at 20 after a duel over a woman.
I wonder, is it ironic that an icon of women in STEM careers died of something that a man could not die from?
*This is not true, just a myth.
