Taking Thread - Sound-Waves on a Cord, 1922
EDITORS COMMENTS
is an intriguing photograph that captures the essence of innovation and scientific discovery during the 1920s. The image features Mr. W.F. Croll, a pioneering inventor, holding a delicate thread with sound waves visibly etched upon it. This thread, a revolutionary alternative to the commonly used disc and cylinder records for sound recording and reproduction, offers significant advantages in terms of space and weight savings. The thread, which appears to be made of cellulose, is adorned with a series of undulating waves, a testament to the successful capture of sound-waves. The photograph also reveals several diagrams and apparatus in the background, suggesting the complex machinery involved in this groundbreaking invention. Croll's invention, known as the Paralograph or Photomicrograph, was a significant departure from the traditional recording methods of the time. Instead of using discs or cylinders, this method employed a thread to record and reproduce sound. This innovation not only saved space and weight but also offered the potential for more efficient and versatile sound recording and reproduction. The image captures the moment of discovery and the excitement that comes with pushing the boundaries of scientific knowledge. The intricacy of the thread and the detailed diagrams in the background underscore the intricacy and complexity of the invention. This photograph is a fascinating glimpse into the past, offering a unique perspective on the history of sound recording and the pioneering spirit of the 1920s.
