Background
The name of this individual appeared on an Okudagram that appeared on Picard's desk monitor, and was not verbally referenced on screen. A legible version of the Okudagram would appear in the reference book, Star Trek: The Next Generation - The Continuing Mission.
The real-life Winrich Kolbe is actually a director of many TNG-era Star Trek episodes.
