I'm pretty sure it's the same person, DMcG. Here's a March 1983 report of Dr. Schrauzer's research and activities:

Schrauzer was a CTR Special Projects Researcher. (N.M. Tobacco Companies Personnel List)
.... Dr. Schrauzer in 1981 for a two-year investigation into the presence of selenium (an anti-carcinogenic trace element) in tobacco smoke. Reports return of unexpended $10,000 to CTR following one year's research. Describes Dr. Schrauzer's current interest in international data collection "to compile a comprehensive data bank of lung cancer risk factors and perform statistical calculations to test various etiologic models."

And perhaps not surprisingly:

They have knowledge and/or participated directly in the tobacco industry's suppression of scientific research, directed the Center for Tobacco Research (CTR) special projects and conspired to wrongfully employ the attorney/client, and/or attorney work product privileges to prevent the production of tobacco industry documents.

I still don't quite understand who was suppressing what, but I've found nothing to indicate that Dr Schrauzer himself was responsible for any wrongdoing.
