From the early 1950s to his untimely death in April 1992, Dr. Levin was an internationally known telecommunications expert and an influential voice in regulatory and antitrust matters. The author of five books, most notably The Invisible Resource – Use and Regulation of the Radio Spectrum, he published numerous scholarly papers on public policies towards television broadcasting, space satellites and the radio spectrum resource, in an array of journals and books. He was Senior Research Associate at the Center for Policy Research, and often served as a consultant to governmental agencies, including the Federal Communications Commission, the U.S. Department of Justice, the Federal Trade Commission, and the U.S. Congress. He was also a prominent member and frequent conference panelist of numerous national and international organizations in communications, economics, public policy and global affairs. His work was supported by such institutions as the National Science Foundation and Resources for the Future.

According to members of his field, Dr. Levin was ahead of his time in fervently addressing issues of the radio spectrum long before anyone, except industry engineers, was concerned with them. "His work focuses on the politics of the airwaves," said Mr. Levin, a New York City government official. "It illustrates, through strict scientific data, how a limited resource can be allocated fairly, with global rather than nationalistic interests, and how programming can be based on diversity rather than profit." One of Dr. Levin’s last projects involved getting countries with satellites in orbit above less-industrialized nations to pay a kind of rent. "He continued to penetrate its frontier," said Mr. Levin, "even after the field evolved into the highly pertinent one it is today – an evolution due, in large part, to his own contributions." Such achievements impelled Dr. Levin’s election to membership in the Cosmos Club in Washington, D.C., an association of persons deemed to "have done meritorious original work in science, literature, or the arts, or… recognized as distinguished in a learned profession or in public service." They also earned him an invitation in 1986 to place his papers in the Archive of Contemporary History at University of Wyoming, devoted to "the history and development of individuals who have played a prominent role in the twentieth century’s social, political, legal and economic scene."

Dr. Levin’s professional library was also donated by Mr. Levin to CITI and Hofstra University Library, as memorial collections.
