1858–1935
A determined freethinker and peace campaigner, she built a public life of her own while growing up in one of Britain’s best-known secularist families. Her writing and organizing kept humanist, anti-war, and reform ideas in view across the late Victorian and early 20th-century years.

by Hypatia Bradlaugh Bonner, J. M. (John Mackinnon) Robertson
Born in London on March 31, 1858, she was the daughter of Charles Bradlaugh, but sources describe her as much more than a famous reformer’s child. She became known in her own right as a British peace activist, author, atheist, and freethinker, and later married Arthur Bonner.
She lectured, wrote, and organized around secularism, human rights, rationalism, and peace. Humanist sources also note that she became an important interpreter of her father’s legacy, publishing major work on his life and career, including Charles Bradlaugh: A Record of His Life and Work.
Remembered as a steady voice in radical and humanist circles, she combined public advocacy with clear, practical writing. She died in London on August 25, 1935.
