The eminent theoretical physicist John Archibald Wheeler who coined the terms black hole, wormhole and quantum foam, has died aged 96.
Wheeler was a driving force in the Manhattan (A-bomb) and Matterhorn (H-bomb) projects and collaborated with Einstein on unified field theory. Wheeler taught many famous students, including Kip Thorne and Nobel laureate (and personal favourite of Mr Reid) Richard Feynman.
Edit: The New York Times and especially Cosmic Variance have fantastic obits.
