Born in Chile to Hungarian parents, Mahr’s family returned to Hungary after World War II ended. She studied at the School of Journalism in Budapest and worked as a photojournalist in the 1960s. In 1972 she moved to London where she completed her studies at the Polytechnic of Central London and embarked on a different approach to photography. She consciously slowed her work down from the speed and immediacy of photojournalism by exploring the difficulty and subtlety of earlier photographic processes. Mahr’s photographs concern memory and she incorporates objects she has inherited and cherished. She constructs (rather than reconstructs) memory by re-associating these objects with places photographically.
