The idea of the establishment of Osogbo Grammar school was mooted by a group of Christians, who were members of All Saints' Anglican Church, Osogbo, about the year 1943. The Osogbo Secondary School Movement was formed under the Chairmanship of one Mr. Lewis, a government pharmacist then at the Osogbo General Hospital. Other members of the movement included the Reverend R.A Ashley- Dejo, then the Vicar of All Saints' Church Osogbo; Messrs John Koledowo; Thomas Ajani (Alaran and later Baba Ijo of All Saints' Church Osogbo); Moses Oladipo (Tailor of Olobu Compound Osogbo); Adeleke Laniyan; Inspector J.A Ajan; Ayo Oyaniyun; P.A Mosadomi; Reverend Maxwell; D.B Ladiran; Mrs. Fabiyi (late Iya Ijo of All Saints' Church, Osogbo); and Mrs. M.L. Odetola (mother of Professor Tunde Odetola) - all of blessed memory.
