Joseph Chike Edozien
From Wikipedia, the free encyclopedia
Joseph Chike Edozien (born 1921 in Asaba) is the provincial ruler (also known as an Asagba) of Asaba, Delta State, Nigeria. The African Mathematics Union suggests that he is the first sub-Saharan African to hold a doctorate in mathematics.
His father was Nathaniel Okafor Edozien, a direct descendant of Nnebisi (the founder of Asaba) and one of the most senior indigenous officials of the Nigerian Coal Corporation in Enugu. His mother, Nwakuso Edozien (née Odogwu), was the daughter of a prominent Asaba chief, and a notable trader.
