Images from Mary Mandels' career. Dr Mary Mandels was one of Natick's original employees of the Pioneering Research Laboratory. Her research included screening fungal cultures for their ability to produce cellulase and related enzymes. The purpose of the research was to increase the understanding of the deterioration of materials caused by fungal attack.
