First stop: OOPSLA '97. Erich gave a tutorial on "advanced design
with patterns and Java":
But that page has no link back to him. So we continue. Next stop:
Object Technology International.
in 1997 where he gave a talk on "Framework Development with Pattens and
Interfaces - the Feel of Java vs. Smalltalk." Mighty buzzwordy, but
okay, at least we know he's still in the pattern area. But this
document has no link to Erich, either. Or does it? A search of OTI's
complete Web presence brings us to:
which is a press release June 17, 1997:
> Dr. Erich Gamma, an internationally respected expert in the software
> industry, has joined OTI as the STC Technical Director. Dr. Gamma
> previously held key technical positions at IFA, Taligent and
> Ubilab. His work on design patterns and frameworks is internationally

> advanced products in Switzerland. Our Swiss partners have the
> foresight to invest for the future so that they are ready for the next
> generation of software applications."
But it still doesn't tell us what he's currently working on. Back to
Altavista. I find the "object oriented FAQ" off Ralph Johnson's page
but find no mention of Erich. Another link back to OTI...
> "I came to OTI because of the amazingly good image it has in the

Ugh. Around Altavista slot 80 out of 1000 we find PhD student Bernard
and he wrote a paper on ET++ with Erich in 1996. But no links to Gamma.
When we try to find more info about ET++
we discover that they think Erich is at Taligent. Clearly this is out
of date information. Back to Altavista baby.
Even ECOOP '96 shows that Erich has no Web page:
Sigh. Even Grady Booch won't tell me where to find Erich:

Okay, let's look at Erich's "Extension Objects Pattern"
> The Extension Objects Pattern
> Erich Gamma
> IFA Consulting

> CH-8034 Zurich

Nope. And he's nowhere else in PLoP '96:

Wonderful. I start out looking for Erich Gamma and end up with a
Cringely quote on Java being the Pascal of the 90s.
I'm guessing that Erich and his new project doing thin X clients are
just not on the Web. Too bad, I would have been interested in reading
The pendulum has gone full circle.
