Johnson, who was also known for her public housing project designs, became famous for her “large-scale public projects, which often involved environmental remediation. For the Mystic River State Reservation, a nature preserve in Eastern Mass., a commission she received in the 1970s, she transformed a toxic landfill into a public park. The John F. Kennedy Park along the Charles River in Cambridge, Mass., had once been an oil-soaked storage site for train cars before Ms. Johnson’s firm took it on in the early 80s.” – The New York Times
