Egyptian scientist
Mahmud Ahmad Hamdi al-Falaki (1815-19 July 1885) was an Egyptian engineer, mathematician and scientist. He was born in al-Hissa, Gharbia Governorate.
He was Egypt's representative at the Third International Geographical Congress and Exhibition, Venice, Italy, 1881. Mahmud Ahmad Hamdi al-Falaki also excavated and surveyed Alexandria in 1866 for producing a plan of the ancient town. His plan was later dismissed in the English speaking world as unreliable (while continental European archeologists and historians used it). Recent discoveries confirmed that the plan made by Mahmud Ahmad Hamdi al-Falaki is reliable.
