Doctor Moritz Benayoun was a male Human physician that lived during the late 24th century. He was an old friend of Jean-Luc Picard; they had together served aboard the USS Stargazer and remained friends for decades afterwards.
In 2399, after meeting Dahj Asha, retired Admiral Picard, hoping to gain Starfleet's permission to be reinstated to active duty, sought out Dr. Benayoun to certify him as fit for interstellar service. (PIC: "Maps and Legends")
