Reuben Olembo was born on November 28, 1937, in
Bunyore in the then Vihiga District of Kakamega in
Western Province, Kenya. He excelled in his studies at Kima Primary School, and then Maseno School, both of which were
mission schools. Faith played a key role in his early family life and education. His parents were both ministers in the
Church of God, established in his village by American missionaries. Olembo was among the first cohort of students airlifted to the US in 1959 as part of the
Kennedy- Mboya airlifts, having rejected an opportunity to study at Cambridge University in the United Kingdom. He attended
Purdue University in
Indiana and between 1961 and 1965 he was awarded his bachelor's (Biology and Chemistry), master's and doctoral degrees (genetics, with minors in biochemistry and statistics). His academic accomplishments were notable because "he did not come from a scientific background and had no laboratory experience." He introduced new, rigorous courses in genetics at both the undergraduate and post-graduate levels. Olembo was a strong advocate for education in Kenya and neighboring countries. He served as an examiner for the Cambridge University School Certificate, a chief examiner for the East African Examinations Council, and an external assessor for university degrees in Nigeria, Ghana, and Tanzania. He wrote and was widely published on genetics, ecology and environmental policy. ==International career==
