Active in the 1860s and 70s, the New York firm of Asher & Adams produced some of the most detailed and colorful late 19th century American Atlases. Asher & Adams are known for their remarkable state and county atlases which are so detailed that they include individual family homes and names. The Asher & Adams firm followed the quality and style formats pioneered by the earlier Colton and Johnson firms - notable for their distinctive pastel color washes and impressive size. Their most important work is their 1874 Asher & Adams Commercial and Statistical Gazetteer of the United States which is one of the first 19th century atlases to remove topographical information to make room for detailed depictions of railroads.
