IIRC, he was at the university of Erlangen at the time and the "posse"
consisted of just him and a second guy (Rainer Pruy).  The CS department
there was (and still is) running a stratum 1 timeservice across several
independent servers and clocks.  Way back in time you'd have to arrange
with them to use it for syncing (generally only if you were on the DFN
backbone to provide stratum 2 service to a university network), now it's
a public service available via NTP pool.  They've also built their own
radio clocks and developed the Erlangen time stamp format, which is now
also used on commercial clocks (Meinberg is now defaulting to it, some
other clocks can optionally output it).
