*Wild Visionary* reexamines the life and work of Maurice Sendak through the lens of his identity as a Jewish gay man. Maurice (Moishe) Bernard Sendak (1928–2012) was a passionate, romantic, and surprisingly humorous seeker of truth who made significant contributions to modern literature and culture. By elevating the standards of children's literature, Sendak depicted childhood with a blend of dark realism and vibrant imagination, influenced by his own sensitive 'inner child' and the queer and Yiddish sensibilities that defined his unique voice. Golan Y. Moskowitz intricately weaves together literary biography and cultural history, tracing Sendak's journey from his parents' Brooklyn home to various creative havens—from local movie theaters to Hell's Kitchen, Greenwich Village, Fire Island, and the Connecticut country house he shared with his partner of over fifty years, Eugene Glynn. Additionally, he delves into Sendak's deep connection to the concept of the endangered child, exploring its symbolic ties to significant historical events that shaped the artist's worldview, including the Great Depression, the Holocaust, and the AIDS crisis. Through a thorough examination of Sendak's picture books, interviews, and previously unexamined personal letters, *Wild Visionary* presents a nuanced portrait of one of the most cherished and captivating picture-book artists of our era.
