David Speiser is Professor Emeritus at the Catholic University of Louvain, where he taught mathematics and physics from 1963 to 1990. His work in history of science included various publications, some of which are related to art history. Nephew of mathematician Andreas Speiser, David Speiser's own wide-ranging interests have brought him into contact with a panorama of disciplines. Editor Kim Williams has assembled a group of notes where scholars contribute essays inspired by their contact with Prof. Speiser in honour of his eightieth birthday. Topics range from history of sciences to history of art, from architecture theory to music theory, from particle physics to the proliferation of nuclear weapons, to an essay on the very nature of interdisciplinary studies.
