The New York Times revealed that an influential psychiatrist who was the host of the popular public radio program “The Infinite Mind,” produced by Lichtenstein Creative Media, earned at least $1.3 million from 2000 to 2007 giving marketing lectures for drugmakers, income not mentioned on the program.

The psychiatrist and radio host, Dr. Frederick K. Goodwin, is another in a series of doctors and researchers whose ties to drugmakers have been uncovered by Senator Charles E. Grassley, Republican of Iowa, according to the Times.
