After studying at the Prilidiano Pueyrredón School of Fine Arts, María Chester decided to deepen her studies in Art History at the UBA-University of Buenos Aires, Argentina. Once there, she also decided to study Archaeology which allowed her to specialize in the pre-Hispanic cultures of America. This combination of studies gave her the possibility of a unique insight into her first passion: rock art. The point of view of an art historian and that of an archaeologist helped her to present master classes on these subjects. María is multilingual and likes to travel to discover new cultures. She taught at various public and private universities. Since 2007, she is the National Subject Advisor on Ancient Civilizations of the Americas for The Third Age Trust, which the umbrella for more than one thousand individual’s U3As in the United Kingdom. She also belongs to the International Committee (of which she was a founder) at the same organisation. (www.u3a.org). In May 2016, María was appointed Secretary General of AIUTA, the International Association of Universities of the Third Age and since then she has worked hard to impulse the movement around the world. (www.aiu3a.org). Since 2017, she has been teaching courses on Art History for BEA-Berwick Educational Association (www.berwickea.org) which in association with the Berwick Visual Arts organizes lectures and guided tours on exhibitions organized at The Granary Gallery in Berwick upon Tweed, England. Maria does the research and prepares the talks on these specific topics. In October 2018, she was awarded with her accreditation as a Lecturer by The Arts Society in London, to which a few belong (only 300 in the entire UK). In 2020, she was invited to be part of the team of lecturers at Art Historical London, which organizes talks and virtual seminars on different aspects of art. (www.arthistoricallondon.com).
