Professor Dr. Bernd Wegner was born in Berlin in 1942. He is professor for mathematics at the Technical University of Berlin since 1974. His main research papers are in the areas of geometry, mathematical relativity, topology, convexity, discrete mathematics and structural foundations of mathematics. He was supervisor of several PhD theses and habilitations, some of them in foreign countries like Spain, Poland, Portugal, Turkey, or Egypt. He was organizer of several international conferences in mathematics. He is member of the editorial board of several international journals in mathematics. For almost 40 years he served as Editor-in-Chief of Zentralblatt MATH, the most complete reference database in mathematics. For a shorter period he was in charge of editing MathEduc, a similar service for education in mathematics. As a consequence he took part in or was leader of several projects improving the availibility of mathematics in the web. The subjects were integrated access to distributed electronic resources in mathematics, distributed database production in mathematics, recognition of mathematical formulas in the web and their transfer to computation and automatic theorem proving, development of a digital mathematics libraries by digitally born or retro-digitized matheatical publications. He is still involved in the further development of the mathematics subject classification and its transition into a flexible web service.
