A visionary impresario, Martin Friedman created the Minneapolis Sculpture Garden and transformed Walker Art Center from a regional venue into an international powerhouse of innovation.
During his 30 years as director, the Walker expanded from painting and sculpture to theater, dance and film. It showed Picasso's private hoard of art before it debuted in New York, hosted movie star Clint Eastwood, staged shows by Laurie Anderson and David Byrne, and welcomed Friedman's pal Vincent Price.
Friedman died Monday at his home in New York City. He was 90 and had lived in Manhattan since his retirement from the Walker in 1990.
At the Walker, Friedman mentored a generation of curators and directors who went on to run major museums in New York, Los Angeles and Detroit. And he was the prime mover behind the museum's brick-clad wing whose minimalist galleries were revolutionary when they opened in 1971.
"Martin understood that the power of a museum comes from giving voice to artists as well as showcasing their art," said Adam Weinberg, director of New York's Whitney Museum and a Friedman protégé. "He was a major voice for artists and a real champion of freedom of expression."
Friedman had recently undergone chemotherapy treatments but congestive heart failure was probably the proximate cause of his death, said a family friend. His death was announced by his daughter Lise.
"It's all so bittersweet," said Walker director Olga Viso, who is scheduled to break ground Tuesday on a $10 million renovation of the Minneapolis Sculpture Garden.
The garden, which opened in 1988, was a capstone of Friedman's tenure as Walker director from 1961-1990. He loved working with artists and commissioned signature sculptures, including the "Spoonbridge and Cherry," by Claes Oldenburg and Coosje van Bruggen, that became a Minneapolis icon and popular selfie site.
