To the world, Louis Armstrong is iconic—a symbol of musical genius, unparalleled success and unassailable character. To Sharon Preston Folta, he was, simply, Dad. Despite the enduring celebration and study of Armstrong’s life and career, no one, save for close family and friends, knows Sharon exists. Even in the trumpeter’s death she remains Armstrong’s secret—the product of a two-decade-long affair between the long-married musician, and the vaudeville dancer Lucille Preston. And for more than half a century, she has lived her life hiding in the shadows of her father’s fame. Until now. Now, Sharon shares her story—extraordinary because of who her father was, but universal in its reach toward generations who have grown up in fatherless households, searching for a keen understanding of their own blood, their own DNA, their own Legacy. Little Satchmo is an extraordinary tale of identity, loss, and one daughter’s ultimate search for truth—and her father’s love.
