In Memoriam Herman F.M. Peters, Ph.D.

Herman PetersOn June 24, after a brief but devastating illness, Herman Peters passed away. In 1989 he was one of the founding members of the International Fluency Association (IFA) and become the 3rd IFA-president in 1993. He served this organization in various roles, including treasurer, and was honored for his contributions to IFA in 2000. Herman started his career as a clinical psychologist, and he specialized in the diagnosis of speech and language disorders. Specifically, he had  a passion for understanding the underlying causes of stuttering and  providing  the most effective treatment for people  suffering from this speech disorder. In the early 1980s, he introduced the Precision Fluency Shaping Program ( the “Webster therapy”) in the Netherlands. In addition, he invited many renowned therapists and researchers from all over the world in order to implement new developments on speech and language disorders in the Netherlands.
