Vienna city mayor Michael Hupl has announced his intention to make the Austrian capital a centre of knowledge, research and science, as it was prior to 1938 when the Nazi takeover forced many academics and scientists into exile. Vienna has nine public universities, six technical schools and five private universities, while private institutions also play an important role in research and development, employing a total of around 6,000 scientists. German pharmaceutical giant Boehringer-Ingelheim, which employs 1,700 people at the Research Institute of Molecular Pathology (IMP) at the Campus Vienna Biocentre, site of the recently opened anti-cancer research facility, has also developed shared research initiatives with the Austrian Academy of Sciences. The city of Vienna invests 150 million annually in research and science projects.
