Development of the Phonograph at Alexander Graham Bell's Volta Laboratory: Contributions from the Museum of History and Technology, United States National Museum Bulletin 218, Paper 5, (pages 69-79)

"Development of the Phonograph at Alexander Graham Bell's Volta Laboratory" by Leslie J. Newville is a scientific publication written in the mid-20th century. The book explores the innovative work done by Alexander Graham Bell and his associates in developing the phonograph, a pivotal technology in sound recording and reproduction that significantly improved upon Edison's earlier inventions. The narrative provides insights into the collaboration and experiments that took place at Bell's Volta Laboratory, highlighting the technological advancements made and the eventual commercialization of these groundbreaking inventions. The content of the book chronicles the establishment of the Volta Laboratory Association and the key figures involved, including Charles Sumner Tainter and Chichester Bell. It details the challenges and experiments the team faced in transforming Edison's tinfoil-based phonograph into a more efficient wax recording device. The text covers their early designs and experiments with various forms of sound recording, including disc and cylinder types, leading to the filing of critical patents in 1886. Newville provides a historical context for these developments, examining not just the inventions themselves but also the social and economic factors that influenced their success. Ultimately, the book illustrates how the work done at the Volta Laboratory laid foundational principles that contributed to the modern sound recording industry.
