The scientific work of Beno Eckmann covers a wide field of mathematical thinking including topology, geometry, homological algebra and group theory, to just name a few. In his work, he went directly to the heart of the problem and presented his solution with elegance and precision. He influenced many fundamental developments of modern mathematics. He contributed definitively to algebraic topology and was one of the founders of homological algebra, of category theory and of the cohomology theory of groups. Beno Eckmann was especially devoted to the education of doctoral students, advising more than 60 doctoral theses. Many of his students became professors at universities throughout the world. His impressive "doctoral family tree", which was compiled by his students in Barcelona for his 80th birthday, contains five generations of mathematicians and names from five continents.
In addition to his purely scientific work, Beno Eckmann accepted many other duties. He was Chairman of the department of mathematics and physics at the ETH Zurich from 1954 to 1956, President of the Swiss Mathematical Society from 1961/62 and Secretary of the International Mathematical Union from 1956 to 1961. Beno Eckmann was also active in the field of scientific publishing. For many years his was one of the editors of the famous "Gelbe Reihe", the "Grundlehren der mathematischen Wissenschaften" of Springer Verlag. In 1964, he founded the Springer "Lecture in Mathematics", a series which facilitated quick publication of mathematical results. Without a doubt his biggest achievement outside of his academic responsibilities was the establishment of the Forschungsinstitut für Mathematik at ETH, where he served as Director until his retirement. In the beginning, the Institute served to facilitate the scientific exchange so important for mathematics and to promote the international collaboration of the members of the department. From these small beginnings, the institute grew into a center of mathematical research renowned worldwide. In the summer of 2004, its 40th anniversary celebration attracted famous mathematicians from all over the world.
The national and international esteem for Beno Eckmann can be seen in the many honors he received, including honorary doctorates of the Université de Fribourg, the EPFL in Lausanne, the Technion in Haifa and the Ben Gurion University in Beersheba. He was named honorary president of the International Mathematical Congress 1994 in Zurich.
His former students, colleagues and friends will remember Beno Eckmann not only for his important influence on the mathematical life at ETH, but also as a helpful, kind and modest man of great personal integrity.
