Yes - just about everyone is mourning the passing of Steve Jobs, but less public fervour has been made of Dennis Ritchie's recent death.
Just about everyone who has learnt to programme at University will have been introduced to the C programming language in the seminal text, know affectionally as Kernighan & Ritchie, I have my precious copy still in near mint condition with a sticky-backed plastic cover on to strengthen it, alongside it sits my other precious book, The UNIX programming environment by Briane Kernighan and Rob Pike, both of whom have paid their very personal respects to Dennis Richie.
This is my small thanks to the contribution that Dennis Richie has made to the world of computing, without his work I would have not had the C programming language, UNIX operating system and my career as a software engineer. Thanks and God bless. Wired puts the contribution he made much better than I could.
