BARTHOLD GEORG NIEBUHR, one of the painstaking historical students whose work has revolutionized the modern historical method, was born at Copenhagen, August 27th, 1776; but he is more closely identified with Germany than with Denmark. In 1806 he left the civil service of his native country for that of Prussia. He served as Prussian embassador at Rome (1816–23), but the great work of his life, his “History of Rome,” was more directly due to the demands of his work as a university lecturer at Berlin and Bonn. The first volume of the “History” was published in 1811 and the last in 1832, a year after the author’s death, which occurred January 2d, 1831. His miscellaneous writings were collected and published,—the last volumes in 1843.
