The Activist Who Helped Bring Curb Cuts to America's Streets

One night in the late 1960s, Hale Zukas and several fellow University of California, Berkeley students slipped out of their residence lugging sledgehammers and chisels. Their target wasn't a building or a statue—it was the curbs that prevented wheelchair users like them from moving freely around campus.

The students lived in Cowell Hospital, a campus residence for disabled students. Frustrated by an environment designed with little consideration for people with mobility challenges, they chipped away concrete curbs, creating makeshift curb cuts where none existed. The group, which became known as the Rolling Quads, helped launch Berkeley's independent living movement, whose ideas would spread nationwide. Their late-night exploits became campus lore, a vivid example of the philosophy that guided Zukas throughout his life: If society built barriers, disabled people could organize to remove them.

Over the next five decades, he helped transform disability rights from a largely overlooked cause into a civil rights movement that reshaped American campuses, public transit and accessibility standards. Though Zukas rarely became the public face of the movement, he played an essential role in building the institutions and policies that continue to shape everyday life for millions of Americans with disabilities.

“The brilliance of Hale and the Rolling Quads was that they re-envisioned who they were: as oppressed people, as talented people pushed to the sidelines unnecessarily. And they really weren't going to stand for it,” says Scot Danforth, professor and assistant dean of research at Chapman University and author of An Independent Man: Ed Roberts and the Fight for Disability Rights.

Born in 1943 with cerebral palsy, Hale Zukas enrolled at Berkeley as a math major minoring in Russian, graduating with honors at a time when few universities welcomed students with significant disabilities. 

Cerebral palsy greatly impaired his speech. Although he could communicate verbally with people who knew him well, he usually relied on augmentative and alternative communication, using a helmet-mounted pointer to select letters and commonly used words on a communication board attached to his wheelchair. “It was an extremely slow form of communication for such a brilliant strategizer and thinker,” says Danforth, a leading scholar of disability studies. “I can guarantee he was frustrated.” 

Because speaking publicly for Zukas required considerable time and patience, other leaders—including fellow Berkeley student Ed Roberts and East Coast transplant Judy Heumann—became the movement’s best-known spokespeople. Zukas instead became one of the movement’s indispensable behind-the-scenes leaders, developing strategy and mastering the technical work that helped turn the disability rights movement's ideas into lasting institutions and public policy.

During the late 1960s, Berkeley had become one of the nation's epicenters of student activism. As demonstrations over free speech, the Vietnam War and the embattled People's Park transformed the campus, students residing at Cowell Hospital were building a movement of their own.

They gathered around the hospital-dorm’s communal dinner table, met over pizza and beer at nearby restaurants and bonded over shared experiences of discrimination, low expectations and social isolation. Those friendships evolved into the Rolling Quads, a group that fundamentally challenged prevailing ideas about disability. 

"At the time, disability was perceived as an illness that would not heal, and disabled people were seen as tragic," Danforth says. "Your job as a disabled person was to accept that with a cheerful attitude and stay hidden so that other people didn't feel bad."

The Rolling Quads rejected that view. Rather than seeing disability as a personal tragedy, they argued it was a civil rights issue. For generations, Americans with significant disabilities had often been expected to live in hospitals or institutions, with major decisions made on their behalf. The Berkeley students instead insisted that disabled people should control where they lived, how they worked and what services they received—a philosophy later encapsulated by the disability rights movement's rallying cry, "Nothing about us without us."

Rather than accepting exclusion, they argued that inaccessible buildings, transportation systems and public policies—not their disabilities themselves—prevented full participation in society. 

The Rolling Quads quickly began transforming Berkeley itself. Together they established the university's Physically Disabled Students Program, providing services and accommodations designed and run by students with disabilities, rather than administrators or medical professionals. 

In 1972, Zukas helped found Berkeley’s Center for Independent Living, the first organization of its kind. It provided peer counseling, advocacy and practical support that enabled people with disabilities to live independently within their communities rather than institutions. Hundreds of independent living centers in the United States and around the world have drawn inspiration from the Berkeley model. 

As the center's first community affairs coordinator, Zukas focused on making Berkeley's physical environment more accessible. Among his achievements: He successfully pressed the city council to install curb cuts along the city's major thoroughfares—the nation's first widespread program of its kind.

Berkeley’s disability-rights movement soon expanded onto the national political stage. In 1973, Congress passed the Rehabilitation Act, which included Section 504—the first federal civil rights provision prohibiting discrimination against people with disabilities by institutions receiving federal funding. But it remained largely unenforced because successive presidential administrations failed to issue the regulations necessary to implement it. 

“Section 504 could have happened under multiple presidents,” says Maria Town, president and CEO of the American Association of People with Disabilities. “The final regulations could have been signed by Nixon; they could have been signed by Ford. This dragged on for three different administrations,” she says.

Frustrated by years of delay, disability activists—led by Zukas, Ed Roberts, Judy Heumann and others—pressed the Carter administration to act. Their campaign culminated in the landmark 26-day sit-in at the federal building in San Francisco in 1977, where roughly 100 protesters refused to leave until the regulations were signed.

The victory established Section 504 as a cornerstone of disability rights and laid much of the legal foundation for the Americans with Disabilities Act, enacted in 1990.

Zukas focused on translating those broad civil rights victories into practical everyday improvements. A power wheelchair user who regularly rode Bay Area Rapid Transit (BART), Zukas became a leading advocate for accessible public transportation. He helped create BART’s accessibility task force in 1975 and earned a reputation for practical problem-solving. “He designed BART’s first curb cut out of wood and duct tape,” says Danforth. And he redesigned buttons in BART elevators so they were reachable by wheelchair users.

His expertise earned him a presidential appointment to the federal Architectural and Transportation Barriers Compliance Board, where he helped shape national accessibility standards governing sidewalks, pedestrian crossings and public transportation. 

“What are the standards for audible pedestrian signals? Where should they be put onto the poles? How high should the volume be so that it can be heard appropriately over traffic?” says Town. “Hale became a part of the body that created those standards.” By ensuring that disabled people helped write the policies affecting their own lives, Town adds, he established an expectation that accessibility should be shaped by lived experience rather than outside assumptions. 

By the time of his death from heart failure in 2022 at age 79, the one-time guerrilla curb-cutter had become an internationally recognized expert on personal assistance services, mass transit accessibility and eliminating architectural barriers.

Yet Zukas knew the fight for inclusion required constant vigilance. Richard Scotch, professor emeritus at the University of Texas at Dallas whose scholarship focused on disability policy, says accessibility can easily backslide when disabled people are excluded from planning decisions. He points to mailboxes, street signs and other public infrastructure installed in ways that block curb cuts as examples. “A lot of people don’t really understand curb cuts, and as a result, they reestablish the barriers,” says Scotch.

Keenly aware that disabled people often lived shorter lives, Zukas had little patience for backsliding or slow-moving bureaucracy. “Every day when Hale got up, he knew that the day was about fighting. There were no days off,” says Danforth. “If a city or county official agreed to take action on a Friday, Hale was back at the office on Monday to say, ‘So, what have you done?’” 

In the 2017 short documentary Hale, filmmaker Brad Bailey asks Zukas why he didn’t give up. Hale types out: “I did not want my style cramped.”
