Roger Leir

Roger Leir was an American podiatrist and ufologist, known for his research on alleged alien implants in humans. Born on March 20, 1934, in San Francisco, California, Leir studied at the California College of Podiatric Medicine and received his degree in 1961. He practiced podiatry for over 40 years in Ventura County, California.

Leir’s interest in the UFO phenomenon started in the 1990s, after he witnessed a UFO event. He became an active member of the Mutual UFO Network (MUFON), a non-profit organization dedicated to the scientific study of UFOs, and eventually became the state section director for Ventura and Santa Barbara counties in California. He also founded the First Contact Foundation, a non-profit organization aimed at promoting research and education on the subject of UFOs and extraterrestrial life.

Leir’s most notable work was his research on alleged alien implants in humans. He claimed to have removed and analyzed over a dozen of these implants, which he believed were of extraterrestrial origin. Leir argued that the implants had unique properties that could not be explained by known science, such as the ability to emit radio signals, emit electromagnetic fields, and contain isotopic ratios that are not found on Earth. Leir hypothesized that these implants served as some sort of tracking or monitoring devices, used by aliens to study the human race.

Leir’s work on alien implants has been met with both praise and criticism from the scientific community. While some UFO researchers have supported his claims and cited them as evidence of alien visitation, mainstream scientists have dismissed his work as pseudoscience and argued that there are more plausible explanations for the alleged implants. For example, some skeptics have suggested that the implants may be ordinary objects such as metal shavings or splinters that became lodged in the body and were mistaken for alien technology.

Despite the controversy surrounding his work, Leir published several books on the subject, including “The Aliens and the Scalpel” (1999), “Casebook Alien Implants” (2000), and “UFO Crash in Brazil” (2004). In addition, he appeared in several documentaries and was a frequent guest on radio shows and podcasts.

Facts about Roger Leir and his work on alien implants are:

1. Leir claimed to have worked with several respected scientists and medical professionals, including Dr. Alex Mosier of the University of California, Dr. Robert Koontz of the University of Wyoming, and Dr. Roger K. Leir, a renowned orthopedic surgeon and his cousin.
2. In 2008, Leir’s team conducted a study on alleged alien implants using X-ray fluorescence analysis, a non-destructive analytical technique that can identify the elemental composition of materials. The study found that the alleged implants contained a variety of elements, including iron, titanium, and aluminum, but the researchers could not confirm that they were of extraterrestrial origin.
3. After Leir’s death in 2014, his research on alien implants was continued by other researchers, including Dr. Christopher C. Green, a physician and biochemist, and Dr. Steven Colbern, a physicist and radio host. In 2019, Green published a paper in the Journal of Scientific Exploration, in which he argued that some of the implants analyzed by Leir’s team contained isotopic ratios that were inconsistent with Earth-based materials.

While there is no consensus among experts on the validity of Leir’s claims, some have praised his dedication and passion for the subject. In a review of “The Aliens and the Scalpel,” UFO researcher Richard Dolan wrote, “Dr. Leir is not only sincere, but he is dedicated to the scientific method in his approach to the study of the implant phenomenon. Whatever one may think of his conclusions, he deserves credit for his courage, his willingness to go public with his findings, and his commitment to scientific inquiry.”

On the other hand, some scientists have been critical of Leir’s methods and conclusions. In a review of “The Aliens and the Scalpel,” astronomer and skeptic Phil Plait wrote, “There are a number of problems with Dr. Leir’s conclusions, not the least of which is that they are based on anecdotes and not hard evidence.” Plait also criticized Leir for not using proper scientific protocols and for relying on subjective interpretations of X-rays and other medical data.

In addition to his books and research, Leir was the subject of several news articles and interviews. In a 2008 article in the Los Angeles Times, he described his work on alien implants and his belief that they were evidence of extraterrestrial life. The article also quoted skeptics who criticized his claims and argued that the implants could have more mundane explanations.

Leir’s work on alien implants has also been featured in several documentaries, including the 2005 film “Patient Seventeen,” which followed his investigation of a man who claimed to have an alien implant in his leg.
