Dr. Norbert Bischofberger (born 10 January 1956 in Mellau, Austria) is an Austrian scientist and one of the inventors of the antiviral drug Tamiflu generically known as oseltamivir, which is, as of 2009, the only oral medication on the market to treat influenza A and B as well as the 2009 Pandemic H1N1 (swine flu), the spread of which caused an ongoing pandemic in 2009.

[2] He worked as part of the DNA synthesis group at Genentech from 1986 to 1990, before joining Gilead in 1990 as Director of Organic Chemistry.

In 1996, clinical studies were carried out on the drug, which was the first orally active commercially developed anti-influenza medication.

Explaining the motivation behind this, he said, "We decided to create a pill and not a medication to inhale because especially people who suffer from influenza struggle with breathing difficulties.

[1][5] Bischofberger has publicly displayed pessimism over the risk viruses pose, saying, "I think the threat by new bacterial or viral agents is higher than the potential of a nuclear war.
