Eduardo R. Callaey was born in Buenos Aires in 1958. He was inducted into the Masonic Order in 1989 and has presided over various Lodges. As a historian he has dedicated the past 20 years to studying the origins and history of Francmasonry. His research has produced valuable contributions in the field of Masonology, particularly with regards to linking primitive Francomasonry with the religious and military orders of the Middle Ages. His position on the religious origins of the Masonic Order has created great controversy as he is one of the key scholars on Christian Masonry in Latin America. He is the author of various books and over a hundred articles on Francmasonry. His most important works include Monjes y Canteros (Buenos Aires, 2001), Ordo Laicorum ab Monacorum Ordine (Academy of Masonic Studies, Buenos Aires, 2004), Los orígenes Cristianos de la Francmasonería (Buenos Aires, Kier, 2006), El otro Imperio Cristiano (The Other Christian Empire, Nowtilus, Madrid, 2005), and El Mito de la Revolución Masónica (The Myth of the Masonic Revolution, Nowtilus, Madrid, 2007). These last two works have been translated into Italian (Marco Tropea Publishing) and Bulgarian (Ciela Publishing House).He has served as Editor-in-Chief for the Masonic journals Símbolo and Magister. Currently he is Editorial Director for the collection Masonry in the 21st Century from Kier Publishing. He is a founding member and former secretary of the Academy of Masonic Studies of Buenos Aires (Academia de Estudios Masónicos de Buenos Aires) and is a member of the Research Center on Historic Studies of Spanish Masonry (Centro de Estudios Históricos de la Masonería Española).
