Leo Zonneveld served the British government for most of his life, including science attaché at the British Embassy in the Hague, where he initiated the formation of bilateral research networks between top scientists in Britain and in the Netherlands, particularly concentrating on the neuro- and biological sciences. His deep interest in the life and work of Pierre Teilhard de Chardin, S.J., has been strengthened by the emergence of the latter's theories in current scientific developments. Zonneveld was also privileged to enjoy a long friendship with the late Pierre Leroy S.J., Teilhard’s friend and companion for many years.
As honorary professor at the Faculty of Psychology and Social Sciences, Leo Zonneveld serves on the International Advisory Committee of the Universidad de Flores, Buenos Aires, Argentina. He has also been an active conference organizer at United Nations in New York; author and editor of several books and professional papers dedicated to the humanities, science and philosophy, including two books on Teilhard de Chardin entitled "The Desire to Be Human"(1983) and "Humanity’s Quest for Unity" (1985); and another on Thomas Paine, entitled "In Search of the Common Good," co-edited with Joyce Chumbley (2009).
Leo Zonneveld contributes to the philosophical series on phenomenology entitled Analecta Husserliana (edited by Anna-Theresa Tymieniecka) and is executive editor of "Reshaping the Human Condition: Exploring Human Enhancement," a co-production weighing possible theories on the future of humanity, under the auspices of the British Science and Innovation Network and the Parliamentary Office of Science and Technology, London, and published by the Rathenau Institute, the Hague in 2008.
