Photographer and English sculptor born in 1813 and died in 1857 in Great Britain.
In addition to this double professional facet, Archer was apprenticed to platero. He/She began to design and sculpt reliefs for medals and coins, and later opened a business of sculpture which made life-size busts. In 1847, to obtain photographs of his designs, he/she began working with the calotype photographic process.
In 1850 he/she published his discovery of the use of pyrogallic acid as a developer or "positivador"; in 1851, he/she proposed a new method for Collodion wet, well experienced, which was published in a note of the English magazine The Chemist. This method represented a step in the history of photography, as it had greater perfection than the Daguerreotype and fifteen times less than this exhibition. A year later, in 1852, he/she published a detailed manual of the process with a small income, since its previous publication not provided him any benefit, since it had not patented it.
Archer died poor and very young, at the age of 44; a year later passed away his wife. The lack of financial resources was that many of his inventions not could be patented. After his death, many historians and photographers have recognized Archer the authorship of many photographic inventions patented by others.
