Harvard University just celebrated its 375th anniversary. But the Sesquicentennial of the Civil War is also of importance to Harvard President Drew Gilpin Faust. A noted historian and scholar of the Civil War, Faust will speak in April at the Boston Public Library as part of the Lowell Lecture Series. Her lecture will focus on the  latest of her six books “This Republic of Suffering,’’ which examines the effects of the war’s enormous death toll. There’s a quick interview with Faust in a recent Boston Globe book section where she talks about her own reading habits. Check it out here at boston.com. I love that fact that she’s a detective story addict – she started with Nancy Drew!
