Eben Alexander, M.D., was an academic neurosurgeon at Brigham Women’s and Children’s Hospital in Boston for many years, and taught at Harvard Medical School. He thought he knew how the brain and mind worked until a transcendental near-death experience during an inexplicable brain infection changed that completely. His book, Proof of Heaven: A Neurosurgeon’s Journey into the Afterlife, has spent two years on the New York Times best-seller list and has been published in 43 countries.
