Ralph Griswold died
Didn’t realise that. He developed some really excellent programming languages. My first exposure to his work was when I downloaded a port of the Icon interpreter for RISC OS. I remember being impressed by how it did a few simple things that no other language at the time (or even now) did to improve readability, such as being able to write things like 3 < x < 9 rather than x > 3 and x < 9, its scanning facilities, its support for generators (something Python has only just caught up with), and so on.
