1919–2001
A nuclear physicist with a gift for clear explanation, he also had deep roots in science-fiction fandom and wrote occasionally under the pen name Lee Gregor. His work bridged hard science, skepticism, and the long-running fan culture that helped shape American science fiction.

by Milton A. Rothman
Born in Philadelphia on November 30, 1919, Milton A. Rothman became a U.S. nuclear physicist and college professor whose career combined research, teaching, and public science writing. He is remembered not only for physics, but for making difficult ideas accessible to general readers.
Rothman also played a notable role in science-fiction fandom. He helped found the Philadelphia Science Fiction Society, widely described as the oldest continuously running science-fiction club in the United States, and he published some fiction under the pseudonym Lee Gregor. The mix of scientist and fan made him an unusual and lively presence in both worlds.
Later in his career, he wrote skeptically about paranormal and pseudoscientific claims, applying the tools of physics to questions that often attract more heat than evidence. He died on October 6, 2001, leaving behind a reputation for clear thinking, curiosity, and enthusiasm for science in many forms.
