Tunji Braithwaite was born in 1933, the youngest son of eight children. He was educated at the prestigious C.M.S Grammar School, entering the school’s Preparatory Section in 1946 and completing his education there in 1953. He proceeded to sit for his A Levels at the London University at Kennington College in 1955 and enrolled in 1957/58 as a Law student at the Council of Legal Education, London. He was admitted into Lincoln’s Inn that same year and graduated as a barrister in 1960.
From his early career as a brilliant young lawyer through to his old age, Braithwaite was constantly confronted with numerous social ills and the pervading corruption which have become entrenched hallmarks of Nigeria. He began his legal career in 1961 with the establishment of the law firm Tunji Braithwaite & Co and quickly earned himself a reputation of being one of the brightest and best lawyers of his day.
With an impressive clientele base comprising the likes of multinational giants Swissair, BASF, Hoescht and Julius Berger, he built up an an enviable law practice and carved a niche for himself as a leading litigation lawyer. Consequently, he successfully handled several landmark cases including the celebrated Treasonable Felony trials of 1962/1963 and State vs Eyo which brought further acclaim to the firm and later in 1974, remarking on his conduct of State vs Olabisi Ajala, Chief Obafemi Awolowo said, “I think Tunji is a brave lawyer of whom our profession should be proud”.
