John W. Sidle - Microscope Maker

Sidle began making microscopes, first in partnership with Poalk, in Philadelphia, and then as "John W. Sidle & Co, Lancaster PA". His several models of 1880 were called the "Acme", and some of his ads referred to the "Acme Optical Works", Lancaster, PA. In 1881, James W. Queen & Co. took over the marketing of Sidle's Acme microscopes, which they continued to sell into the 20th century.
