Alfred Bray Kempe

Alfred Bray Kempe (1849 - 1922)

* 6 July 1849, † 21 April 1922

Alfred Bray Kempe was born on 6 July 1849 in Kensington, London, England. Alfred Kempe published a false “proof” of the four colour theorem in 1879 which stood until Heawood showed the mistake 11 years later. The ‘proof’ is however still the basis for the computer aided proof discovered 100 years later. Alfred Bray Kempe died on 21 April 1922 in London, England.
