Re: Picardo: I Think I?ve Got The Worst Part
From Swam in Season 2
ZIMMERMAN: Don't touch that!
TORRES: Who are you?
ZIMMERMAN: I'm a holographic recreation of Doctor Louis Zimmerman, the creator of the Emergency Medical Hologram.
TORRES: You're the diagnostic matrix.
Louis Zimmerman was also the name of the human character the Doctor assumed in Projections. They probably referenced him as the creator of the EMH at some point.
