Raymond M. Keogh is a graduate of agricultural science, University College Dublin. He is best known for his international work with teak, which began in the 1970s when he joined the UN in Central America. His extensive experience in tropical forestry; his involvement with local communities; his marriage into Salvadorian society and a lifetime dedicated to exploring his own family’s complex social histories, became the ideal blend in which to develop the original concept of our Common or Universal Identity. The adventure that led to the discovery of this revolutionary idea is outlined in his book Shelter & Shadows. Raymond’s other writings include peer-reviewed scientific publications, family history and the novel, Letter to Prosper.
