G.W. & C.B. Colton & Co. was a prominent American mapmaking and publishing company that operated primarily in the 19th century. The company was founded by George W. Colton and his brother Charles B. Colton, both of whom were skilled cartographers and publishers. The Colton name became well-known for producing high-quality maps, atlases, and geographical works.
Foundation and Operations:
- The company was established in 1831, originally under the name Colton & Co., later changing to G.W. & C.B. Colton & Co. as it grew.
- It was based in New York City, one of the major publishing hubs in the United States during that time.
Maps and Atlases:
- The Colton brothers are best known for publishing detailed atlases, maps, and other geographical works that were widely used throughout the United States.
- Their maps covered various subjects, including political, historical, and topographical maps of the world, continents, and the United States.
- Colton was particularly noted for creating maps that were highly accurate for their time, and they gained a reputation for craftsmanship and detail.
Role in American Cartography:
- G.W. & C.B. Colton & Co. played a key role in the development of American cartography. They published detailed maps and atlases that were used in schools, government offices, and by the general public.
- Their “Colton’s Atlas of the World” was one of the most widely used atlases in the 19th century.
Innovation and Contribution:
- The company was innovative in the sense that it employed advanced engraving techniques for its maps, which allowed for greater accuracy and detail. They used steel engraving, a method that enabled sharper and clearer images compared to earlier woodblock printing.

Success and Legacy:

Later Years and Transition:
