Smedley Dynamometer

Usage conditions apply
Fred W. Smedley, Director of the Chicago Child-Study Department in 1899-1901, devised an adjustable stirrup grip dynamometer, as other forms were too difficult for small children to use. This example measures up to 100 kg. The inscription reads “C. H. STOELTING CO. / CHICAGO, ILL. USA / MADE IN U.S.A.”
The C. H. Stoelting Company was formed in Chicago in 1886, and was soon the largest supplier of psychological and physiological test apparatus in the country. It boasted, in 1930, that Smedley’s hand dynamometer was used “in virtually all of the Child Study Departments of the Boards of Education and in fact wherever a test is made of the strength of grip.”
