Leonard George Horowitz (born June 20, 1952)[1] is a dentist, a health industry entrepreneur, author and AIDS conspiracy theorist[2] who opposes vaccination.



From 1978 to the mid-1990s, Horowitz wrote several articles on dentistry, including its relation to medical marijuana and holistic health.[3][4][5][6]

Other works[edit]

Horowitz's self-published books include Deadly Innocence: Solving the Greatest Murder Mystery in the History of American Medicine (1994), and Emerging Viruses: AIDS & Ebola — Nature, Accident or Intentional? (1996), which advances the theory that AIDS and Ebola were engineered by the U.S. government with biological warfare and genocide in mind.

In 2001, Horowitz published "Polio, hepatitis B and AIDS: an integrative theory on a possible vaccine induced pandemic" in the controversial non-peer-reviewed journal Medical Hypotheses.[7]

Kimberly Bergalis controversy[edit]

HIV/AIDS and dentistry received attention in the early 1990s with the case of Kimberly Bergalis, one of six patients reported to have contracted HIV from an HIV-infected dentist, David J. Acer. Initial inquiries concluded that the patients had the same strain of HIV, and that Acer was the most likely source of infection.[8] In 1994, Horowitz wrote that the case should be treated as serial homicide,[9][10] concluding that Acer had acted with murderous intent and was motivated by a political agenda.[11][12][13] At an AIDS conference, Horowitz, Strecker, Cantwell, Vid, and Grossman's names were attached to an abstract that stated that "two-thirds of African Americans recently surveyed believe the AIDS epidemic may be genocide."[14] According to Horowitz, various levels of government had acted in concert to suppress evidence in the Acer case:

"Three years into the Acer investigation, I had fallen deeply into a U.S. Government cover-up... [t]he Centers for Disease Control and Prevention (CDC) and Florida health officials had covered up almost all of the incriminating evidence linking Dr. Acer to thirty six serial killers studied by the FBI."[15]

"I was forced to conclude the authorities covered up the evidence implicating Dr. Acer to prevent the media, and subsequently the public, from probing into his background. The legal testimony in the case indicated he believed he was dying of a virus that the government had created. Dr. Acer, his best friend testified, believed that the virus had been unleashed for genocide against America's gay community and Third World Blacks."[15]

While researching the Acer case, Dr. Horowitz came upon a 1970 Department of Defence appropriations request for $10 million for a five-year study to develop an immune system ravaging microorganism for germ warfare. This project was authorized by the most esteemed of all scientific agencies in America, the National Academy of Sciences and the National Research Council.[16]

However, the "best friend" cited by Horowitz, Edward Parsons, is actually reported to have said "only that Acer was angry about his AIDS infection, and he specifically said that Acer did not tell him that he was going to intentionally infect patients."[17] and that "Dr. Acer had said to him in 1988 that mainstream America was ignoring AIDS because it affected mostly homosexuals like himself, hemophiliacs and drug addicts."[18]

Vaccinations, HIV/AIDS and racial controversies[edit]

Horowitz is the most publicized proponent of the conspiracy theory that HIV was deliberately designed by US military lab in the 1970s for use as a genocidal weapon. The scientific consensus is that HIV is a variation of simian immunodeficiency virus that crossed into humans and mutated into a virus lethal to humans.[2]

Horowitz has been cited as influential in the decision of the Nation of Islam to call for a boycott of U.S.-sponsored vaccination programs:

... Horowitz's account of the genocidal proclivities of governments and pharmaceutical companies has been taken up by the Nation of Islam. As Horowitz relates in the epilogue to the "expanded Reference Edition" [of Emerging Viruses] published in 1998, he was invited by Alim Muhammad, health minister of the Nation of Islam, to address a meeting headed by Louis Farrakhan. Convinced by Horowitz's account of the dangerous contamination of vaccines by unknown or possibly man-made viruses, the Nation of Islam recommended the black community should boycott all compulsory vaccination programs for children in the U.S.[19]

On April 27, 2008, Jeremiah Wright, during questions and answers at the National Press Club in connection with the general controversy over his opinions, was asked by a moderator, "In your sermon, you said the government lied about inventing the HIV virus as a means of genocide against people of color. So I ask you: Do you honestly believe your statement and those words?" Wright responded, "Have you read Horowitz's book, "Emerging Viruses: AIDS and Ebola," whoever wrote that question? .... I read different things. As I said to my members, if you haven't read things, then you can't – based on this Tuskegee experiment and based on what has happened to Africans in this country, I believe our government is capable of doing anything."

On October 7, 2009, Horowitz told al Jazeera that H1N1 vaccines would cause sterility, as part of a plan of "pangenocide" against Muslims. Horowitz was a speaker at Conspiracy Con in 2001, 2004 and 2007.[20]

Claims of a treatment for SARS[edit]

Six weeks after the initial identification of the virus causing the 2003 SARS outbreak, Horowitz and some associates promoted what they claimed was an "effective treatment" for the disease, a naturopathic product line called "Urbani".[21][22] Carlo Urbani, who had first identified SARS to the World Health Organization as a new, infectious and lethal disease after it had spread from China to Vietnam, had died of SARS on March 29, 2003.

The U.S. Food and Drug Administration (FDA) warned Horowitz that his marketing of purported remedies for SARS violated regulations.[23]

Solfeggio frequencies[edit]

Horowitz, along with Joseph Puleo, proposed a set of musical pitches in 1999, which they call "solfeggio frequencies." These pitches, claimed to originate in centuries-old Gregorian chant, are not based in any practical musical tuning, but come from a numerological manipulation of decimal representations of frequencies in cycles per second, or Hertz.

There are many unverifiable claims made regarding spiritual and/or scientific properties of the frequencies. The six "original" frequencies are: 396 Hz, 417 Hz, 528 Hz, 639 Hz, 741 Hz, 852 Hz.[24] The number of pitches has been expanded to nine, then twelve, but the numerical system used to formulate the numbers could be extended further.
