Jerzy Grotowski was a Polish theater director and innovator known for his influential work in the field of theater arts. He founded the Theater of Sources and developed a unique approach called poor theater, which emphasized the actor's physicality and the audience's imagination over elaborate sets and costumes. Grotowski believed in stripping away excess to focus on the essence of performance. His methods have had a lasting impact on contemporary theater and have inspired many artists and directors worldwide. Grotowski's emphasis on the actor-audience relationship and the spiritual aspects of performance continues to resonate in modern theatrical practices.
