What's New?

Eric Saul, the editor of this website, has recently compiled an Encyclopedia of Civil War Biography, which can be viewed on his website It is a comprehensive list of notable Americans from the mid-19th Century. This constitutes a who's who of America in politics, science, industry, and the arts. These individuals represented both sides of the argument over slavery in the United States. Also included is an extensive list of military and naval officers on both sides of the conflict. For those interested in military and naval officers, Union and Confederate, we have compiled an edited version with just entries of those military personnel involved in the Civil War: Encyclopedia of Civil War Military Biography. In addition, this list contains names of prominent Union and Confederate medial officers and personnel.  There are also prominent members of Civil War relief agencies, such as the Sanitary and Christian Commissions.  These entries were drawn from the 1886-1889 edition of Appletons' Cyclopaedia of American Biography (6 volumes). There are more than 3,000 individuals in these Encyclopedias.
