This week on Up Close: Three groundbreaking artists and how their work came into being. "The Threepenny Opera" changed what we think about theater, drama, and music. Author Pamela Katz tells the story behind it in "The Partnership: Brecht, Weill, Three Women, and Germany on the Brink," and Annie Cohen-Solal delves into the rebellious life and work of one of the most distinctive visual artists of the 20th century in "Mark Rothko: Toward the Light in the Chapel."

And then, there are few painters whose work is so distinctive that even a casual observer can instantly recognize their work. Mark Rothko rebelled against the art world to become one of those artists, as Annie Cohen-Solal describes in Mark Rothko: Toward the Light in the Chapel.
