Charles Fasoldt - Microscope Maker

Born in 1819, in Germany, Fasoldt emigrated to America in 1849. While he is most famous for his fine diffraction gratings and micrometer eyepieces, Fasoldt patented a microscope in 1886, especially suited for viewing his glass test plates. Several such microscopes, signed "Charles Fasoldt, Albany, NY" are presently known. Fasoldt died in 1889.
