## John Stallings’ obit in NYT

The New York Times recently published an obituary for John Stallings. He passed away on November 24, 2008. John Stallings is probably most well-known for his work on the high-dimensional Poincaré conjecture. He wrote an article about his work on the theorem called “How not to prove the Poincaré conjecture.” (pdf link)
