- Description
- Frederick A. and Henry Riehlé were Philadelphia businessmen who began trading as Riehlé Bros., in 1867, making and selling scales and materials testing machines. Tinius Olsen (1845-1932) was a Norwegian-born engineer who worked for the Riehlé Bros. in the 1870s, and who would later establish his own material testing machine business.
- This model was probably made in 1871, the year that Frederick A. Riehlé and Tinius Olsen applied for a patent on an improved platform balance.
