He had complications from amyotrophic lateral sclerosis, sometimes known as Lou Gehrig’s disease, said a son, Deen Freelon.
Since 1990, Mr. Freelon had led an architectural firm in Durham that specialized in designing public buildings, including other cultural centers devoted to African American life in Baltimore, Atlanta, Charlotte, San Francisco and Greensboro, N.C.
He led a consortium of several architectural firms — formally known as the Freelon Adjaye Bond/SmithGroup — that won the design competition for the African American Museum in Washington in 2009. Their proposal was chosen, in a unanimous vote, over submissions from renowned architects such as Richard Meier, I.M. Pei and Norman Foster.
Mr. Freelon and the two other principal architects in the group, David Adjaye and J. Max Bond Jr., were black. Bond died in 2009, just before the group won the competition.
Adjaye, born in Tanzania to Ghanaian parents, was the lead designer. As lead architect, Mr. Freelon helped with the design and oversaw the technical aspects of the project, which included negotiating the thickets of bureaucratic Washington. Adjaye described him in 2010 as a “steady rock.”
Over a seven-year period, and at a cost of more than $500 million, Mr. Freelon and his group designed and built the 400,00-square-foot museum, which is adjacent to the Washington Monument. President Barack Obama was present for the museum’s groundbreaking in 2012 and when its doors opened four years later. Since then, nearly 5 million people have visited the museum.

New York Times architecture critic Michael Kimmelman pronounced it “the first really fine major public building of the century to rise in the nation’s capital.”
With its filigreed bronze-colored exterior and its three-tiered corona, derived from a Yoruban architectural element from West Africa, the museum stands in striking — and deliberate — contrast to the white marble edifices of so much of official Washington.
“We wanted the design to be meaningful beyond just a handsome building or a wrap around the exhibits,” Mr. Freelon told the Duke University Chronicle in 2016. “We felt it was appropriate to have something linked to the motherland. This is an African American museum, so the African aspect of it seemed appropriate.”
Every part of the museum’s design had cultural meaning, even the 17.5-degree angle of the edges of the three levels of the corona — exactly the same angle at the top of the Washington Monument, only inverted. The patterns in the building’s metal exterior are based on ironwork African American workers designed and forged for buildings in the South.
“The bronze has a patina to it,” Mr. Freelon told The Washington Post in 2012. “It depends on the sky, the lighting and the time of year to give it a dynamic, changing quality.”
More than an upside-down pyramid, the three-level corona represents “a crown that signifies the status of the person wearing it,” Mr. Freelon added. “It’s part of the celebratory nature of the building — an architectural form that’s uplifting and dignified.”
The museum’s five levels of galleries begin in dark subterranean chambers, telling the story of Africans transported in cargo holds across the Atlantic to enslavement in the New World. Galleries on higher floors depict the path to emancipation, the sorrows and successes of the civil rights movement, and African American contributions to the nation’s culture.
“The African American story is the quintessential American story, even though it was about a forced migration,” Mr. Freelon told The Post in 2012. “America is about opportunity for people from other places. You’ll find the best and worst of what the American story is in the African American story.”
Philip Goodwin Freelon was born March 26, 1953, in Philadelphia. His father sold medical equipment, and his mother was a teacher.
Mr. Freelon discovered architecture in high school and, he told The Post in 2012, considered it “a perfect blend of art and science.”
After attending Hampton University in Virginia, he graduated in 1975 from North Carolina State University. He received a master’s degree in architecture in 1977 from the Massachusetts Institute of Technology, where he said he was often the only black student in his classes.
He worked at architecture firms in North Carolina and Houston before opening Freelon Group in Durham in 1990. The firm grew from a staff of one — Mr. Freelon — to more than 60.
Following his belief that architecture could be a quiet form of activism and education, Mr. Freelon and his firm designed several museums of African American history and culture throughout the country, including the Museum of the African Diaspora in San Francisco, the Amistad Research Center at Tulane University in New Orleans, the Reginald F. Lewis Museum of Maryland African American History and Culture in Baltimore, the Harvey B. Gantt Center for African-American Arts and Culture in Charlotte and the National Center for Civil and Human Rights in Atlanta.
In Greensboro, Mr. Freelon used the Woolworth’s store in which African Americans staged one of the civil rights movement’s first sit-ins to house the International Civil Rights Center and Museum.
In addition to museums, Mr. Freelon worked on the Tenleytown and Anacostia public libraries in the District, a baseball stadium and a bus terminal in Durham, and at least 12 college campuses in North Carolina. After his ALS diagnosis in 2016, he continued to direct several projects, including an expansion of the Motown Museum in Detroit. He also served from 2012 to 2017 on the Commission of Fine Arts, which oversees public building projects in Washington.
In 1979, Mr. Freelon married the former Chinyere Nnenna Pierce, better known as Grammy-nominated jazz singer Nnenna Freelon. In addition to his wife, of Durham, and son Deen Freelon, of Chapel Hill, N.C., survivors include two other children, Maya Freelon and Pierce Freelon, both of Durham; two brothers; one sister; and six grandchildren.
“Each of us has our own perspective on history, and mine is formed by my family, in stories of not just difficulties but also triumph and joy,” Mr. Freelon told the Durham Herald-Sun in 2009, when he received the commission for the National Museum of African American History and Culture. “This museum is about the heroes that are familiar names, but it’s also about everyday people who’ve made an impact on this country, one person at a time.”
