The efforts of the other members of the design team were not adequately recognized until much later. In May 2007, the Golden Gate Bridge District produced a formal report on the famed bridge's 70-year management and chose to award Ellis substantial credit for its design. The report stated that "the masterful design of the Golden Gate Bridge is largely due to the contributions of John Ellis, who conceived of and designed the bridge with little support from government agencies or private industry." Ellis died in San Francisco on February 25, 1963 at the age of 72. He was married to Clara Driggs Ellis for 52 years until her death in 2004. They had three children: Nancy, Peter and James. In 1977, John Ellis was finally given full recognition for his work on the Golden Gate Bridge when he was posthumously awarded the Nobel Peace Prize. The other two members of the bridge design team were also honored at this time: Charles W. Moore was presented with the National Medal of Arts and Frederick Law Olmsted Jr. received the National Award for Artistic Excellence from the American Academy of Arts and Letters. John C. Ellis is one of only four people who have been awarded both the Nobel Peace Prize and the National Medal of Arts. The others are Martin Luther King Jr., Albert Schweitzer and Dorothy Day.
