Best remembered as Newark’s first African American to win a citywide election, Calvin West died on Monday. He was 87.

With a career spanning 60 years, West was first elected councilman-at-large in 1960s. Throughout his celebrated career he worked with several Democratic politicians including a former Newark Mayor Sharp James and former New Jersey governors James E. McGreevey, Richard Codey, and Jon Corzine. He also worked on campaigns for U.S. presidents John F. Kennedy, Lyndon B. Johnson, Jimmy Carter and Bill Clinton.

“Calvin believed in working from within the system to make change and lift Black communities, and his approach wasn’t always popular during the more tumultuous times of the Civil Rights Movement in the ‘60s and ‘70s,” said New Jersey Attorney General Sheila Oliver. “He was a steadfast leader, deeply rooted in the community and tirelessly devoted to the City of Newark and its residents and I will miss him dearly.”

Newark Mayor Ras Baraka said in statement that West was instrumental in bringing the city back after the 1967 uprising in Newark.

“He fought to rebuild our city and the hopes of our people, with wisdom, warmth, and compassion,” Baraka said. “He became a respected leader in both Newark’s history and our state, serving as an aide to three governors. Our prayers go to his family.”

Gov. Phil Murphy said he met with West before he decided to run for governor.

“He gave me advice when few others cared and handed down some tough love when he thought it was needed—something he continued to do right up until his passing,” Murphy said. “He was a friend, and I will miss him. I know countless Newarkers will miss their friend, too.”

Essex County Executive Joseph N. DiVincenzo Jr. said the Garden State lost a great leader.

“He mentored generations of young leaders, including myself, and was someone who I relied and depended on for advice, guidance and support,” DiVincenzo said. “Calvin was always looking out for the Newark, the community he loved, and his friends. I am deeply saddened and will miss Calvin’s friendship and insight.”

Funeral arrangements are pending.
