I read this on reddit, I wasn't even aware of his research, what he found. I found it to be also truly inspiring:
"A great man has passed.
Alas, Ralph Steinman is dead. He died three days before he got the Nobel Prize in Physiology and Medicine in 2011. He dropped out of no college, he did not make a billion dollar company. He did not make billions of dollars, nor even hundreds of millions, though after his death his estate would receive slightly more than a million dollars of the prize money. Yet, he had touched millions, possibly hundreds of millions of lives and will likely touch billions of men women and children in future generations by discoverying one of the secrets of how immunity against viruses or bacteria are translated into an immune response by adaptation of immune cells. How allergy or autoimmune diseases develop, and how immune cells transmit signales to one another. It is possible that it was the fruits of his research that might have extended the life, after pancreatic cancer several years ago, of another giant who died recently. It is also certain that his work has resulted into billions of dollars worth of pharmaceutical industry, and will produce many billions of dollars worth of pharmaceutical industry, and will produce many billions in the future, Such is the reach of a humble life in fundamental science."
