University Libraries Promotion and Tenure Recognition

Ernst Specker has been my favorite teacher since I was an undergraduate student at ETH. Later he became my advisor, and I have learned a lot of him (and still do) about the elegance and beauty of many areas of Mathematics and Computer Science. This collection of his most influential papers reflects his openness, as it covers areas from Topology and Mathematical Logic to Quantum Mechanics and Computer Science. And still, equally impressive has been his involvement in the discussion of political and cultural events of our time.
