[2] Chief Idowu was born in September 1934 at Ikenne, a town in Ogun State in southwestern Nigeria.
Upon completion of his secondary school education, he joined the Lagos State Judiciary in 1958 as a Court Clerk, having decided this to be a pathway to understanding the practice of Law.
He thereafter journeyed to the United Kingdom where he obtained a bachelor's degree in Law from the London School of Commerce and Holborn College.
He was called to the English bar at Lincoln's Inn in July 1962, the same year he returned to Nigeria for legal practice.
In May 1989, he rose to the zenith of his career as Senior Advocate of Nigeria and in 1980, he was elected as president of the Nigerian Bar Association, a position he held until his tenure elapsed in 1982.
