editor and newspaper publisher who was one of the foremost figures in early American journalism.

At age 17 Niles, the son of Quakers, was apprenticed to a printer in Philadelphia, and, upon his release from his apprenticeship three years later, he went to Wilmington, Delaware, and embarked on various ventures, including the publication of a short-lived literary magazine called The Apollo. In 1805 he went to Baltimore, Maryland, and became editor of the Baltimore Evening Post, continuing in that post until 1811. In the latter year he issued the prospectus for his Weekly Register (later to be called Niles' Weekly Register), which he edited and published until 1836 and which became one of the most influential papers in the United States. Niles favoured protective tariffs and the gradual abolition of slavery, and he ceaselessly propaganized for both these causes. Because his articles were regularly reprinted in other periodicals, a common practice of the time, Niles and his paper had a great influence on politics and society. His newspaper remains an extremely valuable source for the study of the political and economic controversies in the United States of his day.
