Cincinnati sisters Anna and Julia Hider (who are two-thirds of a set of triplets) have created the ultimate guide to historic beards. From cavemen to pour-over baristas, beards have been the hallmark of brave, hot dudes. Like most things — porcelain dolls, knickers, cholera — facial hair experienced skyrocketing popularity in the 19th century. Men were willing to experiment with never-before-seen beards (e.g. Ambrose Burnside), including a plethora of Civil War soldiers. In their book, Badass Civil War Beards, the Hiders comment on all the sexy whiskers sported by soldiers for both the Union and the Confederacy. They discuss and sign the book at Joseph-Beth.
