Stanley John Hughes (1918–2019) was a Canadian scientist who is known throughout the global field of mycology for developing and introducing a precise and meticulous system for classifying fungi that is still used today.[1] A naturalized Canadian, he was a federal research scientist for Agriculture and Agri-Food Canada at what is today the Ottawa Research and Development Centre.[2]
Throughout his professional career he made exceptional contributions to the field of fungal taxonomy which significantly advanced this science around the world. His contributions not only benefited his chosen field, but unwittingly, benefited global society by introducing a more sophisticated and scientific method of classifying fungi to enable more in-depth research on moulds.[1] His mentorship of young scientists throughout his career also helped create a new generation of mycology taxonomists dedicated to and enthralled by their research.[1]
