Leonard Horowitz

Leonard Horowitz DMD is a former dentist, public speaker, sound healer, and prolific self-help author who styles himself as "The 'King David of Natural Healing' vs. The Goliath of 'Slash, Burn and Poison Medicine'".Hollywood and Horowitz - Drleonardhorowitz.com He is an adherent and influential promoter of a large range of pseudoscientific conspiracy theories about health and medicine, and is respected among factions of the far right as an authority on these topics.Barkun, Michael (2003).

==Medical misinformation==
===Fear-mongering=== 
Horowitz has spent many years aggressively pushing the idea that vaccines were designed for genocidal purposes,Leonard Horowitz - The Skeptic's Dictionary and that both HIV/AIDS and Ebola were manufactured as biological weapons by the U.S. government.The Origin of Aids and HIV May Not Be What You Have LearnedHorowitz, Leonard (1996). Emerging Viruses: Aids & Ebola — Nature, Accident or Intentional? In this, he has been dangerously influential with some very prominent figures, such as Louis Farrakhan of the Nation of Islam,Muhammad,
 Sultan (2003). AIDS: The Greatest Weapon of Mass Destruction - Final Call, the Nation of Islam's newspaperMuhammad, Starla (2015).
 Viruses as weapons of mass destruction and the fight for optimum health - Final Call.Shabazz, Saeed (2004). Activists charge pharmaceutical cartel with being a tool for genocide - Final Call. whose call for the black community to boycott vaccination was largely prompted by Horowitz's propaganda.Knight, Peter (2013).

Horowitz proclaimed in an interview with Al Jazeera that the H1N1 vaccine would cause sterility,Kane, Sherri. "Al Jazeera Interviews Dr. Leonard Horowitz on H1N1 'PanGenocide'" - tetrahedron.org, 7 October 2009. and is also known to have led Barack Obama's former pastor Jeremiah Wright astray with his misinformation.Nattrass, Nicoli (2013). The AIDS Conspiracy: Science Fights Back, p. 25.
===Alternative medicine===
Horowitz founded the "Healthy World Organization" (HWO) as a "...successful alternative to the corrupt World Health Organization..."The Affiliate Compensation Plan - Healthy World Organization. and he sells products through his company ZeoLife whose mission statement could have come from a New Age bullshit generator: "..to celebrate the manifestation of Divinity in biology, health science, and emerging biospiritual technologies, and through our loving service, deliver the most advanced knowledge and equipment for personal and planetary purification, physical salvation, and spiritual evolution."The Company - zeolife.net.
Soon after the SARS outbreak in 2003, Horowitz began peddling his naturopathic "cure" for the virus, which he called "Urbani SARS formula",Gillis, Justin. "A Rush of Products Ready (or Not) to Fight SARS". Washington Post, 10 May 2003.Dr. Horowitz - AIDS, Ebola, Vaccines, Tetrahedron.com brazenly misusing the name of deceased Italian physician Carlo Urbani who had first reported SARS to the World Health Organization and set off a massive life-saving response worldwide.Dr. Carlo Urbani of the World Health Organization dies of SARS - World Health Organization, 29 March 2003. Unsurprisingly, Horowitz was subsequently issued with a warning letter from the FDA.Breen, Charles. Warning letter to Leonard Horowitz - Casewatch, 19 May 2004.
==Sound healing woo==
Among all the other things, Horowitz is also well-known for promoting conspiratorial woo around the supposed health effects of sound frequencies in music. 
===The A440 conspiracy===
Horowitz is one of the foremost promoters of the A440-tuning conspiracy theory, which he covered in a long and influential 2010 article, demonstratively titled "Musical Cult Control: The Rockefeller Foundation’s War on Consciousness Through the Imposition of A=440Hz Standard Tuning".Musical Cult Control: The Rockefeller Foundation's War on Consciousness Through the Imposition of A=440Hz Standard Tuning Among other things, he claims to have evidence that A440 tuning, when compared to A444 tuning, is "relatively distressing", "conflicts with human energy centers", and causes the body to vibrate "according to an institutionally imposed frequency that resonates in harmony with aggression and in dissonance with LOVE".Capitalization his, of course. He also places the implementation of the tuning system with the Nazis at the beginning of WWII, despite it having been around for long before that, and despite the fact that many countries in the world (including Germany and Austria) use a different system. 
===528 Hz===
Going hand-in-hand with his hatred of 440 Hz, Horowitz is perhaps most famous for promoting the frequency 528 Hz.528 Hz – The Love Frequency In his book on the subject,The Book of 528 he makes many grandiose claims about the number 528 and the frequency 528 Hz, calling it "the universal LOVE constant," "central to Divine creation," "linked to the heart of everything."Amusingly, it seems to have escaped Horowitz that his hated 440Hz and his beloved 528Hz are related by the ratio 5:6, meaning that these frequencies will harmonize together as a (and can coexist perfectly well as the notes A and C respectively in a system). His evidence for 528's magic is a rapid-fire of pareidolic insanity:
* 5 + 2 + 8 = 15, 1 + 5 = 6, 6 is sacred.
* A mile is 5280 feet.
* 528THz is green, the color of grass.
* The movie Inception involves Room 528.
* The golden ratio is indicated by the symbol φ, which is the initial of the Greek word φιλία, which in English is LOVE, and 528 is the universal LOVE constant.
* Pi is related to the golden ratio because you can divide a circle into five equal sections.The pi/phi relationship is bogus, but it is true that phi is related to regular pentagons — it's the ratio of the diagonal to a side.
Horowitz even sells a "528 musical medicine" product called OxySilver, described as "The First Manufactured 'Holy Water' Resonating at the Most Natural and Powerful Healing Frequency of 528Hz Sound and 528nm Light".OxySilver 528 "Holy Water"It is not clear how he can claim both these figures concurrently, because a 528Hz sound wave in the air actually has a wavelength of over 60cm, not 528nm, i.e. a million-fold difference. Even worse, light of wavelength 528nm has a frequency of over 560THz, not 528Hz, which would put him out by a factor of a trillion.
===The "solfeggio frequencies"=== 
Horowitz is also one of the foremost promoters of the "ancient solfeggio frequencies" (396, 417, 528, 639, 741, 852), which are entirely based on numerologyHorowitz himself has taken issue with this statement, correcting us that the frequencies come from "verse numbers in the Bible’s Book of Numbers", which is totally not numerology! and involve a bizarre misuse and redefinition of terminology (including the scale tones "ut", "re", "mi" etc. and the word "solfeggio" itself) from the music education method and its precursors, to the detriment of people who search online for bona fide information about this method. 
He propagates a series improbable claims surrounding these frequencies (e.g. 396 Hz "liberat(es) guilt and fear", 417 Hz "undo(es) situations and facilitat(es) change" etc.)The Ancient Solfeggio Scale and has conducted some "additional research" which has apparently "revealed" three more frequencies (963, 174 and 285), all of which, somewhat predictably, adhere to the same numerological pattern.The Ancient Solfeggio Frequencies - "The Perfect Circle of Sound"

In July 2019, a semi-coherent screed on the site waronwethepeople.com,DR. LEONARD G. HOROWITZ QUACK-BUSTER. GOOGLE BLACK-OP EXPOSED: DR. LEONARD G. HOROWITZ QUACK-BUSTER PROVES COMPANY’S COMPLICITY IN SEARCH-FIXING FOR MIND-CONTROL, SOCIAL ENGINEERING, CONCEALING VACCINE-CANCER LINKS, AND AIDS GENOCIDE. waronwethepeople.com, July 14, 2019. authored by "DR. LEONARD G. HOROWITZ QUACK-BUSTER" (apparently referring to himself in third person throughout the article), expressed dissatisfaction with our coverage here and made some colourful accusations, one of which was that we have been "proven to be criminally operating as a libel mill protecting Big Pharma". This rant is hardly worth commenting on, other than to warn potential readers to hold onto their brain cells (and their sides.)
