Learn about some of the fascinating programs and performances from The Lyceum’s first twenty years. Science was a popular topic for lectures, demonstrations, and exhibits at Lyceum Hall, as it was known in the 1840s and 50s – some of them featuring legitimate academic programs and others featuring the latest pseudoscience crazes of the day. Performers ranged from the scandalous Dionysius Lardner, who lectured at Lyceum Hall on astronomy, to the display of the “Feejee” Mermaid, a hoax made famous by the father of humbug P.T. Barnum. Jim Holloway, facilities coordinator at the Alexandria History Museum at The Lyceum shares his research on the wide variety of science-based entertainments enjoyed by Alexandrians in the two decades before the Civil War. Doors open at 7 p.m., lecture begins at 7:30 p.m. Tickets are $10.
