Judith Tannenbaum (1947–2019) was an educator, speaker, poet, and writer. She shared and taught poetry in schools before finding a passion for prison justice and reform. For decades, she taught arts in California state prison systems in partnership with the California Arts Council and the California Department of Corrections and Rehabilitation.
Through this work, Tannenbaum fostered a 20-year-long friendship with poet Spoon Jackson, and the two recounted their lives and experiences in the double memoir, By Heart: Poetry, Prison, and Two Lives (New Village Press, 2010).
