Theodore Mann, birth name Goldman, (May 13, 1924 – February 24, 2012) was an American theatre producer and director and the Artistic Director of the Circle in the Square Theatre School.
Mann co-founded Circle in the Square Theatre, widely regarded as the birth of the off-Broadway theatre movement with José Quintero in 1951. Ten years later, he established the Circle in the Square Theatre School to provide training for aspiring actors. It presently offers a two-year program including courses in scene study, text analysis, speech, dance, and singing technique.
