James Ramsay MacDonald,
Dictionary of National Biography
(1901)
“ He was soon promoted to the management of the common law department in the office, and while serving in this capacity under various employers he acquired that knowledge of the law which he put to such effective use in the many law cases in which he found himself involved. On his return to London he had entered into the propaganda of freethought and radical principles at Sunday open-air meetings, and to shield himself in his week-day employment adopted the nom de guerre 'Iconoclast,' which he used until his first contest at Northampton in 1868. ”
