I was born in England and worked on my father’s farm from 1955 to 1958. I attended college in England from 1958 to 1961 and obtained diplomas in agriculture and agricultural engineering. From 1961 to 1963 I worked as an Agricultural Extension Officer in Tanganyika during the period when it became independent. I immigrated to the USA in 1964 and attended the University of California, Davis until 1970 obtaining BS and PhD degrees. In 1971 I became a Professor and Crop Ecologist in the Experiment Station at the University of California, Riverside. I worked at UCR on crop physiology and breeding improved cowpea varieties for California and Africa until my retirement in 2003. Then as an Emeritus Professor and Consultant I advised various agencies of the United Nations and development organizations concerning agricultural research for development and wrote and edited various books and reviews.
