Erasto B. Mpemba

Erasto Bartholomeo Mpemba (born 1950) is a Tanzanian game warden who as a schoolboy discovered the eponymous Mpemba effect, a paradoxical phenomenon in which hot water freezes faster than cold water under certain conditions. He discovered the phenomenon at Magamba Secondary School in 1963 while preparing ice cream to earn pocket-money. The correctness of his observations was proven experimentally.[1]

During his studies at the College of African Wildlife Management near Moshi, he published in 1969, together with Denis Gordon Osborne, a paper on the phenomenon.[2] Later he worked in the Department of Natural Resources and Tourism in the Wildlife Division. He has since retired.[3]
