This morning I learned, via Dave Farber's IP list, that Joybubbles passed away on August 8, 2007. Born Joe Engressia, and blind since birth, Joybubbles discovered that his perfect-pitch whistling allowed him to control telephone switching systems, thus giving birth to the era of "phone phreaking." Although I never met Joybubbles, I did encounter many legendary stories, and much respect for him, during my own time in the Computer Underground. An eccentric and unique man that made a lasting countercultural contribution. You can read his NYT obituary for more fascinating details.
