Mathematician
English mathematician who devoted his working life to the Four Color Theorem.
In $1890$, exposed a flaw in Alfred Bray Kempe's proof, that had been considered as valid for $11$ years.
He never actually proved the theorem, which remained open until it was finally proved in $1976$ by Kenneth Ira Appel and Wolfgang Haken.
