Hal Finney, a cryptographer who worked on PGP and Bitcoin, has died at 58 from ALS.  I had the pleasure of working with Hal in IEEE P1619.2, where he wrote a reference implementation of EME2 (a wide-block encryption mode).  I remember that he had a really friendly and positive attitude, even in the presence of others with others in the IEEE standards meetings who were less civil.  Your work will not be forgotten.
