In Memory of Marc E. Fey

The field of communication sciences lost a remarkable leader when Marc Fey passed away on September 12, 2023. At Brookes, we will remember him as the dedicated Co-Series Editor of the Communication and Language Intervention (CLI) book series, which he helped direct and expand for many years. Marc was not only a series editor but also a volume editor/author. One of those titles, Treatment of Language Disorders in Children, now in its second edition and slated for a third, has become a classic text for speech-language pathologists, for its balanced examination of interventions for emerging communication and language as well as more advanced language and literacy. A strong supporter of evidence-based practice, Marc brought his passion for research and commitment to well-designed intervention studies to the selection process for the CLI series. Those books benefited from his keen editorial and writing skills. Our staff who had the pleasure of working with him will remember many enjoyable moments at CLI Board meetings and his collaborative, encouraging leadership. His legacy will live on in the volumes he helped to envision and create for the field, and the difference he made in the lives of so many children with speech and language disorders.
