Antoine Redier (1817-1892) was an innovative clock-maker, credited with the development of the portable ‘bedside’ alarm clock, obtaining twenty-seven patents of invention or improvement for various time-keeping and recording devices. Despite the fame and success garnered during his career, Redier’s life ended in penury, apparently ruined by an unscrupulous banker.
