The repertory model, favored by Brustein, involved a resident company doing plays in rotation. It provided an unusual level of stability for an actor. “It represented a very different way of being able to work, such as having a seasonlong contract with a living wage that you could count on,” explained MacDonald. Many in the company — including MacDonald — were also given the opportunity to teach, following in Brustein’s footsteps.

“Not only does he leave an immense legacy in the theater, he changed the lives of so many of his students, whom he loved,” noted Sam Marks, senior lecturer on playwriting and Paul and Catherine Buttenweiser Director of Creative Writing.

At the same time, Brustein and the A.R.T. also challenged its members, MacDonald said. Recalling tours to England and Scotland as well as the former Yugoslavia during those first heady years, she remembers the young company working with European directors, an experience she described as “exciting and eye-opening. Seeing the way they approach the work, the way their culture and their theater traditions could be melded with ours.”

Back in Cambridge, one rapt member of the audience was Paulus, then an undergraduate. Although she had grown up with theater in New York, “I saw a theater that was truly putting a wedge in my brain about what the theater could be,” she said.

A.R.T. productions involved such innovative directors as Julie Taymor, Robert Wilson, Joanne Akalaitis, and Andrei Serban. “These were bold theatrical visions,” said Paulus, regarding his impact on her as an artist. “He was showing us all what was possible in the theater.”

Throughout his years at the A.R.T. and long afterward, Brustein continued as the drama critic of The New Republic, a position he began in 1959, and also occasionally waded into controversy. For example, the A.R.T.’s 1984 production of “Endgame,” directed by Akalaitis, drew a threat of legal action from playwright Samuel Beckett because its staging and casting differed from the playwright’s very specific directions. The eventual compromise meant including a scathing denouncement from Beckett, and the show went on.

Brustein himself picked a fight with both Yale Rep and the playwright August Wilson when Wilson’s “The Piano Lesson” moved from New Haven to Broadway. Such a commercial move, he said, was “a serious deterioration in the integrity and nature of the resident theater movement.” His further criticism of Wilson’s work resulted in a yearslong feud carried out in both The New Republic and American Theatre magazine, culminating in a “town hall” discussion in 1997.

Brustein would serve as the A.R.T.’s artistic director until 2002, when he was succeeded by Robert Woodruff. Paulus began her tenure in 2008, and (since June 2022) has co-led the theater with Executive Director Kelvin Dinkins Jr. Even after leaving Harvard, Brustein remained an influential voice in theater.

“The theater doesn’t have a required retirement age,” noted MacDonald. “As long as you keep seeking work and creating work and finding work, you can just keep going. And Bob was testimony to that because he was 96, and he still loved to talk about the theater. I don’t think he ever lost that passion and that commitment, and he passed that on to us.”

“His legacy is not only in all the artists that he took chances on and that he supported,” said Paulus. “For me, Bob’s impact was the playground he gave to all these artists. His legacy lives on in so many ways. As a playwright, as an artistic director, as a director, as a writer, as a critic, as a teacher.”
