Dictionary of national biography. Vol. 20. Ubaldini-Whewell

London: Smith&Elder, 1909. — 1398 p.The Dictionary of National Biography (DNB) is a standard work of reference with articles on more than 29,000 notable figures from British history. It was originally published in 63 volumes between 1885 and 1900, by Smith, Elder & Co.The first volume of the Dictionary of National Biography appeared on 1 January 1885. In May 1891 Leslie Stephen resigned and Sidney Lee, Stephen's assistant editor from the beginning of the project, succeeded him as editor.[1] A dedicated team of sub-editors and researchers worked under Stephen and Lee, combining a variety of talents from veteran journalists to young scholars who cut their academic teeth on dictionary articles at a time when postgraduate historical research in British universities was still in its infancy. While much of the dictionary was written in-house, the DNB also relied on external contributors, who included several respected writers and scholars of the late nineteenth century. By 1900, more than 700 individuals had contributed to the work. Successive volumes appeared quarterly with complete punctuality until midsummer 1900, when the series closed with volume 63.
After issuing a volume of errata in 1904, the dictionary was reissued with minor revisions in 22 volumes in 1908 and 1909; a subtitle said that it covered British history "from the earliest times to the year 1900".
