"Matthew Carey Lea, also known, as Carey Lea, son of scientist Isaac Lea and Frances Carey Lea, was born in Philadelphia on 18 August 1823. An acknowledged authority on photochemistry in the late nineteenth century and a member of the Franklin Institute, Lea began experimenting with the chemical properties of developer in 1864. Educated through tutors and the Philadelphia chemistry laboratory of Booth, Garrett and Blair, Lea particularly studied the function of silver in the development process. His scientific advancements of photographic processes included inventing the first mordant-dye picture in 1865 and increasing the clarity of developed dry plate negatives in 1880. Lea also wrote prolifically about his experiments. In 1864–1866, he assumed the position of American correspondent to the British Journal of Photography and became a steady contributor to the Philadelphia Photographer and Photographic Mosaics. In 1868, he authored A Manual of Photography. During the 1870s and 1880s, he continued to experiment with silver halide salts and the color process. On March 15, 1897, Lea died in Philadelphia, two years after his election to the National Academy of Sciences." Erika Piola, p 839 - 840, THE ENCYCLOPEDIA OF NINETEENTH-CENTURY PHOTOGRAPHY.
