Brian Kernighan & Dennis Ritchie

...and I think Larry Ellison (Oracle) will also not be happy, discovering his absence from this list.
The list got allmost everything covered (OS's, Office apps, file sharing, browsing, hardware), but lacks all database related people.

This I think is a great miss. After all, were would we (or for that matter: the web and virtually every business nowadays) be without a database?

Otherwise a fun list to read. I discovered I missed only 2 of the top-15 :-).

The father of the relational database model doesn't rate a mention?

More deserving than several on the list, but thanks for doing it anyway!

How can you forget the, as Time Magazine called him, The Grandfather of Modern Computing?

Also I think is a shame that Seymour Cray was not included.

No one from Linux and Open Source. Visionaries exist in that realm

And what about the guys behind the everywhere used OpenSSH, from Cisco to Linux to *BSDs? Without his desire to improve the entire security of the Internet by eliminating the need for Telnet with it's "in the clear passwords", the world would be much less secure.

I don't know who he might replace on the list of 50, but he should be there.

Donald Davies/Paul Baran ... Alan Turing ... Ada Lovelace ... Tommy Flowers ...

great article-- stirs one to think of the distance we have come, standing on the shoulders of giants, and how we might contribute rather than solely profit .

The other kings of programming languages:
Nklaus Wirth (pascal etc)
Dennis Richie (C)
Bjarne Strousrtup (C++)

Let's not forget the founders of SAP: Dietmar Hopp and Hasso Plattner

Also old-timers like Babbage and Boole (binary, anyone?)

Why don't we add the inventors of the telephone, television etc?

Fifty pioneers... Outrageous!

John Warnock & Chuck Geschke? Adobe have changed the communication landscape via technology out of all recognition. No DTP revolution, no Web publishing revolution.
