In the years following the Civil War, ancestors of documentary filmmaker Peter Kunhardt collected a treasure trove of photographs, rare books and other artifacts relating to Abraham Lincoln. Over the decades, their descendants carried on the work, helping to preserve an essential part of America’s past. The HBO documentary Living with Lincoln, premiering April 13, chronicles how five generations of one American family have shared the “glorious burden” of collecting, preserving and documenting a vital archive relating to Abraham Lincoln.
