The fiddler busking in the Columbus Circle subway station in 1965 is the Dekrepitzer Rebbe, the sole survivor of the obscure Dekrepitzer Hasidic sect known before the war for its rebbes' fiddling. The Last Dekrepitzer follows the life and spiritual quest of Shmuel Meir Lichtbencher a/k/a Sam Lightup, from his isolated shtetl in the mountains of southern Poland, where he is brought up to be the future rebbe, to the wharves in Naples, where he jams with Black soldiers waiting to ship home at the end of the war. Dressing him in the uniform and dog tags of an AWOL soldier, they smuggle him home to rural Mississippi. He lives for years among the Blacks, speaks Black English, preaches and plays the blues with the Brown Sugar Ramblers trio. His marriage to a Black woman, Lula Curtin, legal by Jewish law though forbidden under Mississippi law, results in a cross burning that forces them to flee to Manhattan. He plays on the streets of Harlem and Midtown with the Reverend Gary Davis, the great blind guitarist whose mission is saving souls for the next world. Shmuel Meir's devout wife, though she knows herself to be the Dekrepitzer Rebbitzen, is spurned by the Jewish community. Through it all, Shmuel Meir fiddles his prayers in defiance of God. But God gives the Dekrepitzer Rebbe no peace.

"The Last Dekrepitzer is a remarkable novel about faith lost and regained in the aftermath of the Holocaust. In telling this story of the last surviving rebbe of a Hasidic dynasty passing as a Black street-fiddler, Howard Langer has discovered a new idiom of American Jewish writing. A brilliant re-imagining of the legend of the hidden righteous soul told as though the melodies of Hasidic niggunim were blues." -David Stern, Harry Starr Professor of Classical and Modern Hebrew and Jewish Literature, Harvard University

"How wonderful to see the personality and music of Rev. Gary Davis enter into the world of Shmuel Meir. They wander and play music together on the streets of New York, sharing their thoughts and visions of life. Rev. Davis's spirit lives on and, as he used to say, 'I don't have any children but I have many sons.'" -Stefan Grossman, noted guitarist and author of Reverend Gary Davis: The Holy Blues and Early Masters of American Blues Guitar: Rev. Gary Davis

"This is a terrific book. Beautifully written and cleverly plotted. It surprises the reader with twists and turns but makes the course of events seem perfectly natural. Unlike many authors writing about Jewish matters, Langer brings a wealth of authentic learning to the book, which adds much to the feeling that this 'unbelievable' story of a rebbe without Hasidim is perfectly believable! The book is deeply moving. Themes of astounding loss and a hard-won kind of redemption merge with great power."

"If you liked James McBride's novels about the layered connections between American Jews and Blacks, you will love The Last Dekrepitzer. Shmuel Meir Lichtbencher is an inspired Hasidic rebbe and fiddler, the only survivor of a fictional Polish shtetl. In rural Mississippi, he lives among African Americans and learns their English and music, but his fiddling of niggunim, wordless melodies with which he confronts God, is the universal language that saves him as he traverses post-World War II America. Langer's prose is as inspired as Shmuel Meir's fiddling." -Kathryn Hellerstein, Professor of Germanic Studies (Yiddish), University of Pennsylvania, co-editor of The Norton Anthology of Jewish American Literature
