here is a bit more than i gave earlier a few of the places working on dls in the
70s and 80s.

your search for description logics on google was thwarted because description
logics have had a few names.
kl-one-like systems/languages, term subsumption languages, and  terminological
logics were used for a while.

the best source on DLs is the web page

http://dl.kr.org.

from there you can get to a listing of the history of the workshops from 1980 on
http://dl.kr.org/workshops/index.html
with the first one that actually had description logics in the name being  in
1992  co-located with kr'92 in boston.

another good source on dls is the handbook of dl -
http://books.cambridge.org/0521781760.htm

another good source on dls is the dl reference index from patrick lambrix's
pages - http://www.ida.liu.se/labs/iislab/people/patla/DL/references.html
which is searchable from
http://www.ida.liu.se/labs/iislab/people/patla/DL/form.html

while it is not totally complete, it is not bad at coverage.

also, a partial list of dl researchers is up at:
http://www.ida.liu.se/labs/iislab/people/patla/DL/researchers.html

and an outdated list of some dl systems is up at:
http://www.ida.liu.se/labs/iislab/people/patla/DL/systems.html

hopefully this helps.
