In his time, Ulysses S. Grant was grouped with George Washington and Abraham Lincoln in the "Trinity of Great American Leaders," yet fell out of favor in the 20th century; Lincoln scholar Ronald White argues convincingly that we need to revise once more our estimation of Grant. Based on seven years' research with primary documents—some of them never examined by previous Grant scholars—White shows him as a generous, curious, introspective man and leader, with a natural gift for managing the rampaging egos of his fellow officers. His wife Julia Dent Grant, long marginalized in the historic record, emerges here in her own right as a spirited and influential partner.
