In addition to the city curfew, Mr. Fulbrook's recent battles included one for a referendum seeking nonpartisan elections and one to legalize medical marijuana and open a dispensary in Camden.
A civic watchdog, Mr. Fulbrook always walked from his Cooper Grant home - where he kept copies of the city's master plans, zoning maps, and the dozens of lawsuits he filed over the years - to City Hall for Council and other municipal meetings.
"Whether one agreed with his position on certain issues or not, his passion for Camden and commitment to this city was unquestionable and undeniable," City Council President Frank Moran said in a statement. "His passion and true grit were only matched by his intellectual capacity."
Mr. Fulbrook lived in Williamstown for his first five years. At age 5, he moved with his family to Morse Street in East Camden and never left the city. He graduated from Woodrow Wilson High School and attended Rutgers University-Camden, where he was a member of Tau Epsilon Phi Fraternity.
A lifelong bachelor who never had children, Mr. Fulbrook once worked as a paper handler for Philadelphia Newspapers Inc. He eventually moved to the Cooper Grant neighborhood and bought two houses and a parking lot, which he rented to students.
Mr. Fulbrook cofounded the Cooper-Grant Neighborhood Association and is credited with helping to spur that community's resurgence.
Former Assembly Speaker Joseph J. Roberts Jr. came to live in Cooper Grant because of Mr. Fulbrook's insistence that the neighborhood was on the verge of a turnaround. Roberts had no regrets moving there, even if it meant late-night chats with Mr. Fulbrook.
"I remember nights where I'd be leaving Trenton . . . I'd have a couple bags of food from the supermarket and some clean shirts from the cleaner, and I just wanted to go home and crash, and Frank would be there, and we'd talk," Roberts said Tuesday.
Roberts called Mr. Fulbrook "a full-time professional citizen who did it for the right reasons and had a real profound impact."
Ali Sloan-El, a former city councilman, met Mr. Fulbrook in the early 1980s, when both were entering politics.
"He was a one-man show," Sloan-El said. "I had the army; Frank always had the mind-set."
Sloan-El, who adopted the nickname "the People's Champ," said that he had a following of people but that it was not until he teamed up with Mr. Fulbrook that they were able to make things happen.
"When Frank gets together with people, he is unbeatable," Sloan-El said, pointing to Mr. Fulbrook's victories, including getting nonpartisan elections in the early 1990s and beating the city's previous attempts at enacting a business curfew.
Though he did not have a law degree, Mr. Fulbrook had schooled himself in writing legal briefs and filing his lawsuits on his own.
Most of Mr. Fulbrook's legal fights were paid for with his "personal money and personal time," Sloan-El said. Mr. Fulbrook's income came from renting the three properties he owned next to the Rutgers-Camden campus on Penn Street.
A fount of institutional knowledge, Mr. Fulbrook would stay on the phone for what seemed like eternity with reporters, residents, or anyone who called him, and discuss the history of any particular issue or topic.
A 1981 City Council meeting that included a vigorous debate on a proposed ordinance on rent control led to his activism, he told The Inquirer in 1997.
"It clicked," he said. "I knew I had found my life's work: local government. I felt I had something to contribute."
A former vice chairman of the city Zoning Board of Adjustment, Mr. Fulbrook served on various city boards, including those of the Empowerment Zone and the now-defunct Camden City Library.
Before becoming ill in 2012, Mr. Fulbrook was present at nearly every civic meeting. He always carried a thick folder with papers related to the meeting, as well as a calendar with times for every open government meeting that month.
"He is an angel," said Ilan Zaken, former owner of the Sears building, which Mr. Fulbrook fought for many years to preserve. "He cared for the people more than anything, a very honest, very straightforward man."
The last pillar of the Sears building on Admiral Wilson Boulevard was knocked down last week to make room for an office park.
Mr. Fulbrook is survived by his mother, Bobbie Simon; a brother, Jim; and an aunt, Irene Banks.
Funeral arrangements were pending.
