content: Bausch & Lomb introduced their Physician’s microscope in 1877, boasting that it was “firm and well balanced” and well adapted “to the use of physicians and students.” The stand and case cost $40; with two objectives and camera lucida it cost $65. Ernst Gundlach, the Prussian immigrant who had become superintendent of the firm’s new microscope department in 1876, was largely responsible for the form.
