During the time that I was in the group, it numbered three persons:
with Hans Dietrich (on the right)
at the Berlin Bundesgartenschau, July 1985
with Joachim Schütze
at the FHI Christmas Party, 1984

The research group was dissolved in 1988 when Prof. Hans Dietrich retired.
Some little tricks I did while working in this research group:
How to Apply Vaseline to the Inside of a Sealed Capillary Tip without getting the remaining length of the capillary smudged with vaseline as well.
How to Make a Minitorch with which to simultaneously cut and seal a capillary accurately at desired length
