LEVY, MAX:

American inventor; born at Detroit 1857. He invented the etched screen and the machinery for producing it now generally used in the half-tone process of photoengraving. After serving an apprenticeship of three years with an architect, he became chief draftsman in his brother's (Louis E. Levy's) photoengraving establishment at Baltimore during the early struggle to establish and perfect that branch of the graphic arts. He accompanied his brother to Philadelphia, and for a time was in charge of the entire business. After the introduction of the half-tone process he spent over two years of constant and close application devising and perfecting the mechanism of his new invention. Levy is also an inventor in other lines, and is a constant and indefatigable experimenter.
