What Wikipedia says about Jim Fetzer:
James Henry Fetzer (born December 6, 1940) is the Distinguished McKnight University Professor Emeritus of the philosophy of science at the University of Minnesota Duluth. Since the late 1970s,
Fetzer has worked on assessing and clarifying the forms and foundations of scientific explanation, probability in science, philosophy of mind, and philosophy of cognitive science, especially artificial intelligence and computer science.
In the early 1990s, Fetzer started promoting John F. Kennedy assassination conspiracy theories, later 9/11 conspiracy theories, Holocaust denial, conspiracy theories regarding the 2002 death of Senator Paul Wellstone and more recently Sandy Hook Elementary School shooting conspiracy theories. He cofounded Scholars for 9/11 Truth in 2005, and claims that the United States government, Israeli government and Israeli Mossad are involved in these and other conspiracies. Fetzer’s allegations and speculations have drawn strong criticism.
