The brothers Louis Edward Levy (1846-1919) and Max Levy (1857-1926) founded a photoengraving business in Baltimore in 1875. In 1877 they moved to Philadelphia and reorganized the firm as the Levytype Company. Here they introduced their invention (jointly patented on January 4, 1875) of a new photochemical engraving process, which they called "Levy-type". This album contains personal cyanotype photographs of their homes, travels, friends and family.
