Biography
Born in 1824 in Paris, Adolphe-Alexandre Martin developed a profound fascination for photography from a young age and became an amateur photographer. Later, while serving as a professor of physics and chemistry at the College Sainte-Barbe in Paris, Martin became a member of the committee of the
During this period, Martin was also independently working on modifying the ambrotype photographic process, originally designed by the English photographer Frederick Scott Archer. In his variation of the wet collodion technique, Dr. Martin applied a transparent protective varnish over the negative, which he first applied to glass and then to a metal plate. Subsequently, he applied a colored varnish over the negative, which not only protected the image but also chemically converted it from negative to positive. This variation of the technique became known as the ferrotype (tintype).
On April 18, 1853, Adolphe-Alexandre Martin shared his exciting discovery in a paper sent to the French Academy of Sciences.[1] In it, Dr. Martin explained that his original goal was not only to create a photographic image but also to assist engravers in their work when replacing artists' drawings. For this reason, initially, Martin was more inclined to use plates made of materials that were easier to engrave, such as wood, copper, steel, and not iron, which had become the preferred material for photographers. As the image would be destroyed after the engraving, Martin proposed that a second image be produced on glass so that the design could be reused in the future as a reference.
Dr. Martin quickly recognized the extensive possibilities of using the ferrotype technique. For example, images on glass plates were not easily transportable, whereas those composed on metal or cardboard were. The findings of his research were published in La Lumiere and received widespread attention worldwide.[citation needed] The versatile ferrotype invented by Martin became very popular for its ability to produce affordable, high-quality portraits, which allowed photography to move beyond studio confines and venture outdoors, especially during times of war. In fact, many of the portraits made during this era were created using the ferrotype technique.
In recognition of his contributions and efforts, Adolphe-Alexandre Martin was named a
