Loudspeaker apparatus, 19th century
Loudspeaker apparatus, as constructed in the laboratory of the French physicist Henri Becquerel (1852-1908). This apparatus includes a Ruhmkorff coil (induction coil, top) and was constructed by Becquerels demonstrator Peignot. It was intended for the amplification of voices in amphitheatres and lecture halls, and was known in French as a telephone a haute voix (speaking aloud telephone). Artwork from the seventh volume (first period of 1891) of the French popular science weekly La Science Illustree

EDITORS COMMENTS
This print showcases a remarkable piece of 19th-century technology - the loudspeaker apparatus. Constructed in the laboratory of renowned French physicist Henri Becquerel, this apparatus was designed to amplify voices in large spaces such as amphitheatres and lecture halls. The illustration, featured in the popular science weekly La Science Illustree, provides a glimpse into the fascinating world of early electrical devices. The artwork depicts an intricate arrangement consisting of a Ruhmkorff coil (induction coil) at the top, skillfully crafted by Becquerel's demonstrator Peignot. This mono chrome image captures not only the technical brilliance but also highlights the historical significance of this invention. With its wires and connections intricately woven together, this loudspeaker apparatus represents a breakthrough in sound amplification technology during that era. It is interesting to note that it was referred to as "telephone à haute voix" or "speaking aloud telephone" in French. As we delve into this snapshot from history, we are reminded of how scientific advancements have shaped our modern world. This artwork serves as a testament to both human ingenuity and technological progress while paying homage to pioneers like Henri Becquerel and his collaborator Louis Figuier. Let us marvel at this extraordinary device that paved the way for future innovations in audio amplification and appreciate its place within Europe's rich scientific heritage.
