Карл Рудольф Кёниг: Акустикалық құралдар жасаушысының өмірі мен еңбектері

the Austrian astronomer

Karl Rudolph Koenig (26 November 18322 October 1901) was born in Königsberg of Prussia. Koenig was a businessman, instrument maker, and German physicist, chiefly concerned with acoustic phenomena. He was best known for designing and building acoustical instruments such as the tuning fork and sound analyser.

Karl Rudolph Koening was born on 26 November 1832, a descendant of a prominent Königsberg family. Koenig was raised along with his three sisters by his mother: Mathilde (Preuss) Koenig, who came from a craftsman and musical family background, and his father Johann Friedrich Koenig, a professor of mathematics and physics who had studied under the famous Friedrich Bessel. In 1851, Koenig moved to Paris, living in an apartment along the Île Saint Louis. He lived alone and was never married. Eventually, he turned to focus more on mechanics and physics. In 1968, he was awarded an honorary doctorate at the University of Koenigsberg.

Karl Rudolph Koenig was known to be a great craftsman, but a lesser known interest of his was physics. Sounds in particular were a fascination of his, to the point that he spent a large amount of time and money doing research on acoustics. Early on in life, he took a position as an apprentice in the workshop of violin maker Jean Baptiste Vuillaume. Koenig spent seven years working under Vuillaume until 1858 when he started his own business. The business started in his apartment which consisted of a living room, bedroom, and a workshop along with the laboratory. It was a small and quiet place where Koenig worked with his passion of acoustics and music. He would spend most of his free time and money on this same passion. In 1861, Koenig grasped an opportunity to expand and moved his business to Lycée Louis le Grand/

One of Koenig's more interesting devices was a watch with the escapement consisting of a tuning fork that could calibrate the main frequencies of any sound. This apparatus helped Koenig establish the frequencies of musical tones and allowed him to build a musical scale.

In 1859, Koenig both published his first catalog, and inverted the phonograph which would play a crucial role for the graphical analysis of sound. Around 1860, along with Hermann von Helmholtz, Rudolph Koenig worked to devise an electronically controlled sound. After working alongside him, Koenig became the main maker and seller of Helmholtz's instruments. Two years following this in 1862, he began to exhibit the nano metric flame apparatus (see attached image and description for more information) at the London Exhibition. This was the first time his nano metric flame apparatus was displayed to the public. In 1865,  Koenig published his second catalog, and was awarded a gold medal from the Societe d'Encouragement pOllr l'lndustrie ntuionale for the use of his instruments in working with the study of acoustics In 1867, his apparatus collection was exhibited in Paris. After few exhibitions, many of Koenig's products began to be sold internationally. A few years following in 1868 he presented all this catalog at the Paris universal exhibition where about 70% of his production was sold. After his death in 1901, some of Koenig's equipment was sent and is now maintained in Conservatoire des Arts et Métiers, Paris. The Smithsonian Institution has since began a collection of Koenig's apparatus including some of his tuning forks. These were donated to the museum by the U. S. Military Academy. Another large amount of Koenig's apparatuses is owned by the University of Toronto's physics department.
