Viscount Amberley was a progressive LiberalMP for Nottingham from 1866 to 1868. He had advanced social views: he was an atheist - he wrote a book called Analysis of Religious Belief. His father took steps to suppress it, without success, and his mother helped have it published. He was an advocate of birth control (as was his wife) - his position on this subject cost him his position as an MP. He tolerated the intermittent affair that his wife conducted with their children's tutor, the biologistDouglas Spalding; however her death, and that of their daughter (both of diphtheria), affected him greatly and he died soon after.
