Tintypes: 19th Century to the Present

Thursday, August 13th, 2009

by Beverly Mosman, Assistant Photo Archivist

The last photographic method for mirror and unique images was patented in 1856 by Hamilton L. Smith, a chemistry and physics professor at Kenyon College in Ohio. Originally known as “melainotype” or “ferrotype” these images are more commonly called tintypes. (more…)

Cherokee Certificates

Bill Welge here. One of the disconcerting aspects of looking for Indian ancestors is the lack of census data. The Cherokees began compiling decennial census records beginning in 1880, but prior to that time, census taking was very sporadic.

One way to hopefully locate family members is to search through records other than census materials. As an example, among the court records of the Cherokee Nation there is a list of individuals who were issued certificates for payment for services rendered for the quarter ending December 31st, 1875.* Some 41 men are listed and why they are being paid.

This is just one way to locate family when census records are not available.

* Cherokee National records – Courts document # 532. See microcopy CHN-70.

Cherokee National Orphan Asylum

by William D. Welge, Research Division Director

Bill Welge here with a bit of important genealogical information for those looking for Cherokee ancestors. On microfilm roll CHN – 66 will be several folders regarding the Cherokee National Orphan Asylum. Occasionally the files will include the names of those individuals who are residents at the home. For instance there is a list of 48 females with their names, age, some with date of birth, what district in the Cherokee Nation they were born, their guardian and the guardian’s Post Office address. This is of particular importance because it is in between the Cherokee 1890 census and the United States census of 1900. The youngest resident is 9 years old and the oldest is 19 years old.

Ambrotype Images: 1855-1861

Research by photographers after 1851 led to the development of the Ambrotype in 1854. The Ambrotype used a colloidal emulsion which after processing held the image on glass. A layer of black paint was applied to the back of the glass plate to allow reflected light to display it as a positive image. Usually a brass cover mat and a protective glass plate were placed over the Ambrotype before being sandwiched together inside a protective case the same type and size as the daguerreotype.

The Ambrotype quickly became popular with photographers since the process was easier to prepare and cheaper than the daguerreotype. Production peaked between 1856 and 1857 due to the post production expense of the protective case and the fragility of the image.

Many Ambrotypes are discarded when the black paint on the back side of the glass plate begins to flake. This problem is easily remedied by placing black mat beneath the Ambrotype, emulsion side up. The oval shaped damage in image #23268.CP.A.2 usually occurs when the brass cover mat slides across the emulsion surface on the glass image.

Few examples of Ambrotypes have been found dated after 1864.
