Norman E. Borlaug: 1914 - 2009
I first heard of Norman Borlaug from watching a season one show of Penn & Teller's Bullshit. If you haven't seen it, go watch it somewhere or buy the season. Borlaug's efforts in agriculture saved a *billion* lives.
He died yesterday at 95.
If you don't know about him, go read his bio at the Nobel Prize website - he won the Peace Prize in 1970. It's worth spreading this man's legacy as far as we can; he was a true hero of humanity.
