On April 29th 2017, Thomas Edison National Historical Park hosted a symposium commemorating the 200th anniversary of Edouard-Léon Scott de Martinville’s birth. Researchers shared their latest findings with scholars, teachers, students, writers, documentarians, and others who are rewriting the “origins of sound recording” story. American representatives from the National Park Service, French dignitaries from the scientific establishment, and representatives of the two inventors’ families honored the symposium with their encouragement to craft new, accurate narratives.
