One of Nigeria’s first civil engineers, Igwe Israel Eloebo Iweka (Eze Olodo) (1879–1934), constructed the enormous Iweka Road in Onitsha in 1924. Additionally, in 1922, Iweka translated the first Igbo history from the Igbo language into English.
In 1932, he was appointed warrant chief of Obosi. In 1939, Isaac Iweka, his eldest son (1911–1996), became the first Igbo to graduate with a degree in civil engineering from Imperial College, London.
