Norman Kember

Norman Frank Kember (1931 – September 2025) was a British biophysicist and peace activist. He was an emeritus professor of biophysics at Barts and The London School of Medicine and Dentistry and a Christian pacifist active in campaigning on issues of war and peace. As a Baptist, he was a long-standing member of the Baptist Peace Fellowship of North America and the Fellowship of Reconciliation. As a conscientious objector to military service, he worked in a hospital in the early 1950s, which stimulated his interest in medical physics. He was involved with the "Peace Zone" at the annual Greenbelt Festival.

Kember became internationally known in 2005 when, as a member of a delegation of Christian Peacemaker Teams (CPT) in Iraq, he was taken hostage with three other CPT members, leading to a widely publicised hostage crisis.
