Once a rising star in the Golden Dragons gang, the brilliant super-scientist named Dr. Shinn has dropped out of sight of late. Reportedly, he grew weary of Fung Shu's emphasis on traditional Chinese mysticism and withdrew in disgust. He has been rumored to have said something about various people rueing various things on his way out of the lair of the gang for the last time. He briefly was employed by Gotham University in its advanced physics department, but was fired for unusual unsanctioned experiments. He was reported to have said something about various people rueing various things as he was escorted off campus (much like when he was kicked out of the mayor's office and the offices of Wayne Public Holdings).
Dr. Shinn was killed by vigilantes in July 1934, in the midst of a plot to unleash an army from the Lost Continent of Lemuria onto Gotham.
