Uhh... This is Doctor Elliott, with the official report for the Directorate from BioScience. The date is, umm, August 2178. I'm pleased to report that, as has been the case during my tenure, crop yields exceed expectations. In point of fact, everything down here is fine... with... one notable exception. Doctor Frederick has informed me that the Directorate has pre-approved research on samples of the FEV virus, which he already has in his possession. Now, I'm not one to question the Directorate... you all know that. I don't even want to know where this came from. But... well, this is troubling. Dangerous, possibly. I will do my best to make sure risks are minimized, but I really do hope that the consequences are understood.”— Dr. Elliott - Institute Bioscientist
Dr. Frederick was an Institute doctor in the year 2178. He began the Institute's FEV program after it was approved by the Directorate. He was the first to work on the FEV virus inside the Bioscience division. The goal of the the research was to improve the synthetic organics program that other divisions were working on.
Frederick is only mentioned in Fallout 4.
