An Active Retirement
Ralph may have retired in 1995, but he remained active through 2001 as both of these links attest to:
- http://www.cs.arizona.edu/icon/analyst/backiss/IA66.pdf – the last edition of The Icon Analyst
- http://www.cs.arizona.edu/~ralph/ – Ralph’s last University home page with link to his weaving page
The Third Workshop on the Icon Programming Language (1992) marked the last time that I saw Ralph and his wife. You can read an eight page overview of the conference at http://www.cs.arizona.edu/icon/ftp/doc/ipd206.pdf, including pictures of all the participants. As well as Ralph, his wife and me, I should point out Alan Beale, who was responsible for the last IBM mainframe version of Icon.
