Ricardo Scofidio, an architect who helped reshape the museum landscape in the US, died on Thursday at 89. His death was announced by Diller Scofidio + Renfro, the firm he founded with his wife Elizabeth Diller in 1997.

NEW YORK (AP) — Ricardo Scofidio, an architect who transformed an abandoned railway into New York City’s popular High Line park and was among the first in his profession to win a MacArthur Foundation “genius grant,” has died. He was 89 and had worked on museums, college buildings and other projects around the world.

With his studio Diller Scofidio + Renfro, the designer helped create buildings, parks and spaces that blurred the line between art and architecture.

The Diller Scofidio + Renfro co-founder was behind iconic New York City designs like the High Line and Lincoln Center revamp.
