Chief Sumner Karibi Dagogo-Jack, born in 1930, was the chairman of the National Electoral Commission of Nigeria (NECON) from 1994 to 1998, appointed by President Sani Abacha. He had previously served as a member of the Humphrey Nwosu electoral commission from 1989 to 1993. During his tenure, NECON was criticized for lack of impartiality and being controlled by Abacha. The commission registered five political associations, seemingly devoid of credible politicians, to ensure Abacha's sole presidential candidacy. Despite overstepping its authority, NECON conducted elections for local government councils and the National Assembly. Notably, Dagogo-Jack nullified the positions of elected officers shortly before the March 1997 local government elections. His tenure ended abruptly with the sudden death of Abacha in June 1998, leading to a fresh electoral process initiated by his successor, Abdulsalami Abubakar. Dagogo-Jack hails from Abonnema, in Rivers State, and has family members involved in medicine and governmental roles.

His pivotal appointment as the head of the newly formed Life-Saving Bureau marked the beginning of his influential tenure. Under his leadership, the Life-Saving Service expanded its reach to the Pacific Coast and the Great Lakes, evolving into a well-trained and cohesive organization. Kimball's legacy is honored by the Coast Guard cutter USCGC Kimball (WMSL-756), a Legend-class cutter renowned for its extensive capabilities in law enforcement, coastal defense, and anti-terrorism efforts. Kimball's enduring impact on the U.S. Coast Guard is a testament to his remarkable contributions to maritime safety and security.
