Canada

A piece of French made equipment from the original laboratories of one of Canada's premier research schools. These apparatus derive from the earliest days of physics teaching at Western University in London (1920s). In the late nineteenth century, Canadian scientists such as J.C. McLennan (Canada's first PhD in physics in 1900, U of T) learned the basics of physics using these apparatus. The maker, Rudolph Koenig, was influential in helping Prof. James Loudon establish the first teaching laboratory in Canada in the 1870s and 80s, which was emulated at other schools such as Queen's, Western and McGill. These particular apparatus were probably obtained c. 1920 by Raymond Compton Dearle, who had done a PHD at the University of Toronto under J.C. McLennan. The French connection is also significant. In the late nineteenth century, every college and university in Canada and the United States bought instruments from Paris. They were deemed an essential part of early research and teaching. In the early 1870s, shortly after arriving in Boston, Alexander Bell used the Koenig instruments at MIT for his research on visible speech. He was particularly impressed with the manometric flame instruments and went out of his way to meet Koenig at the 1876 Exhibition in Philadelphia.

Fonction

A device used to demonstrate accoustical properties, in a laboratory or classroom setting.

Technique

This manometric pipe represents the earliest generation of optically based acoustical instruments. This example has a manometric flame capsule and does not appear in the 1889 Koenig catalogue (Ref. 2). Acoustical demonstrations were an enormously popular part of basic science and physics education during the nineteenth century. They were the foundation of fundamental studies in physics, musicology and psychology. Teaching laboratories and conservatories across Europe and North America had large acoustical collections for demonstrating and experimenting with sound phenomena; acoustical instruments were also used extensively for public lectures on "the science of musical sounds." In addition to basic science, physics and psychology, Koenig's acoustical instruments stimulated inventions related to the telephone and phonograph. Alexander Graham Bell used Koenig's manometric and graphical instruments to study "visible speech." Rudolph Koenig (1832-1901) was the most prolific and influential acoustical maker of the nineteenth century. He pioneered graphical and optical acoustics and perfected the making of tuning forks. He began work as a violin maker for J.B. Vuillaume and moved into the precision instrument trade in Paris during its height (1830-1880). His workshop on Quai d'Anjou, which was based on the master artisan model, was a popular meeting place in Paris for scientists, musicians, physicians and science agents.
