Billy Joseph Stanley Oritsesaninomi Dudley (10 November 1931 - 23 December 1980) was a leading Nigerian political scientist, working mostly at the University of Ibadan (UI) , which he joined in 1959. Until late 1962, he was on the staff of the Extra Mural Department of UI, and from 1960 to 1962 he was based in Zaria, where he began the research that he later supplemented with research in London, England, during periods of leave in 1961, 1963, and 1965, each lasting several months. His resulting PhD was published in 1968 as Parties and Politics in Northern Nigeria. He became a Professor at UI in 1971 and Head of department in 1972. Early life Dudley was born at Warri, Nigeria, to Diana Alice Oritseweyinmi Chute. His father was Stanley John Dudley. His early childhood was spent in Warri, in the care of his maternal grandmother. Education He started school in Warri in 1939. In 1943, his grandmother took him to live with his mother and stepfather, who at that time were in Ilesha. He completed the last year of his primary education at Iloro School, Ilesha, then became a boarder at Ilesha Grammar School. After leaving that school in 1949, he returned to the Warri/Sapele area, employed first in palm produce inspection, then for a short while teaching at Zik's College of Commerce. During this time, he used a correspondence course ("Rapid Results") to study further, initially hoping to obtain a degree in economics in this manner. In 1955 he became a student at the University College of Leicester on a government scholarship, becoming "one of a small group of Nigerian students, later to become distinguished academics, who passed through Leicester in the late 1950s and gained a reputation there for outstanding performance (others included J. F. Ade Ajayi and Adebayo Adedeji)." Career Before his final illness, Dudley had started to gather material for a biography of Murtala Mohammed, the Nigerian military president who took over from General Yakubu Gowon after the 1976 coup, and who was assassinated later that year. Dudley's published views on Mohammed indicated that he held Mohammed in high regard. Dudley died in Epping, England. Billy Dudley was one of the co-authors of the 1979 Constitution of Nigeria (since replaced, following various military coups). He is also credited with having been a major influence on the principal advisers to General Gowon in 1967, recommending that Nigeria
