- 1833 – Wilhelm Dilthey, German psychologist, sociologist, and historian (d. 1911).
- 1937 – Penelope Leach, English psychologist and author.
Wilhelm Dilthey (19 November 1833 to 01 October 1911) was a German historian, psychologist, sociologist, and hermeneutic philosopher, who held G.W.F. Hegel’s Chair in Philosophy at the University of Berlin.
As a polymathic philosopher, working in a modern research university, Dilthey’s research interests revolved around questions of scientific methodology, historical evidence and history’s status as a science. He could be considered an empiricist, in contrast to the idealism prevalent in Germany at the time, but his account of what constitutes the empirical and experiential differs from British empiricism and positivism in its central epistemological and ontological assumptions, which are drawn from German literary and philosophical traditions.
Penelope Jane Leach CBE (née Balchin; born 19 November 1937) is a British psychologist who researches and writes extensively on parenting issues from a child development perspective.
Leach is best known for her book Your Baby and Child: From Birth to Age Five, published in 1977, which has sold over two million copies to date and won the BMA award for “best medical book for general audiences” in 1998. Leach notes in the introduction to that book: “Whatever you are doing, however you are coping, if you listen to your child and to your own feelings, there will be something you can actually do to put things right or make the best of those that are wrong.”
