Dr. Norbert Bischofberger, 55, is the inventor of Tamiflu, the only medication on the market to treat the virus. He has made millions from the drug, but colleagues have said it was science, not money, that motivated him.
A graduate of Innsbruck, Zurich and Harvard universities, Dr Bischofberger headed a research team to create Tamiflu, the first orally active commercially developed anti-influenza medication, for US company Gilead Sciences in the 1990s.
But in an interview with a German Sunday newspaper it was reported he "gets quite angry" if it was suggested he had become rich through the deadly virus.
"No person ever said on his death bed: I only wish I had earned more money in my life," he said.
Swine flu has killed more than 700 people globally, and Dr Bischofberger predicted the death toll would rise. He warned that pandemics were one of the biggest threats to the human race.
"I think the threat by new bacterial or viral agents is higher than the potential of a nuclear war."
