Erie County, Pa., was deeply impacted by the Civil War. An anti-slavery stronghold, the county sent two-thirds of its military-aged men to fight, with more than one thousand never to return. George Deutsch, well-known Civil War historian and frequent lecturer at the Chautauqua Institution, will cover Erie’s contributions to the war effort and examine its demographics, economy and politics on Wednesday, April 30, at 7 p.m. in the Alex Theatre. Free and open to the public. Reservations are not required. For more information, call 814-725-6277.
