Dun & Bradstreet

19th century

Dun & Bradstreet traces its history to July 20, 1841, with formation of The Mercantile Agency in New York City by Lewis Tappan. Recognizing the need for a centralized credit reporting system, Tappan formed the company to create a network of correspondents who would provide reliable, objective credit information to subscribers. As an advocate for civil rights, Tappan used his abolitionist connections to expand and update the company's credit information.

Despite accusations of personal privacy invasion, by 1844 the Mercantile Agency had over 280 clients. The agency continued to expand, opening offices in Boston, Philadelphia, and Baltimore. By 1849, Tappan retired, allowing Benjamin Douglass to take over the booming business.

In 1859, Douglass transferred the company to Robert Graham Dun, who immediately changed the firm's name to R. G. Dun & Company. Over the next 40 years, Graham Dun continued to expand the business across international boundaries.
