Person

H. J. L. Struycken was a Dutch otolaryngologist, phonetician, and acoustician. After studying medicine in Groningen, in 1893 he started working at the Voorburg psychiatric hospital near Vught, where he attempted to distinguish psychiatric conditions from neurological speech disorders. His interest in phonetics and acoustics took Struycken to France and Germany, to visit clinics and approach instrument makers who could produce tuning forks for him to use in his clinical research.

After coming to Paris in 1851, Rudolph Koenig trained with the violin maker Vuillaume until 1858, when he launched his own instrument-making business at Place Lycée Louis-le-Grand. Koenig’s workshop participated in Paris’s flourishing activities in scientific research and instrument-making from the 1830s to the 1880s. More specifically, it contributed to the development of acoustics as an independent field of research.

Person

The silk manufacturer Johann Heinrich Scheibler invented a method to tune keyboards with unprecedented accuracy, applying principles that he had developed in his textile factory. His technique involved a set of tuning forks called a tonometer, a chronometer, and the counting of beats. It aimed to deskill tuning so that anyone could achieve precise tuning regardless of their musical ear. He explained his invention in Der physikalische und musikalische Tonmesser of 1834.

Hermann Ludwig Ferdinand Helmholtz, later von Helmholtz, was born in Potsdam in 1821, the son of Caroline Penne and high school principal August Ferdinand Julius Helmholtz. He became interested in natural science at a young age, but followed his father’s wishes and studied medicine at the Berlin military academy. He graduated in 1842.

Person

Karl Rudolph Koenig (also known as Rudolf Koenig or König) studied at the University of Königsberg. In about 1852, he moved to Paris and joined the workshop of famous violin-maker Jean Baptiste Vuillaume. In his leisure time, Koenig attended public lectures and studied mechanics, becoming increasingly interested in acoustics research. After six years of apprenticeship with Vuillaume, Koenig became a master violin-maker, but his own new business was a workshop for acoustic apparatus.
