Mirko Beljanski (27 March 1923 – 27 October 1998) was a French-Serbian molecular biologist who studied bacteria, its resistance to antibiotics and the interaction of RNA and DNA.

After World War II, he received educational offers from the Yugoslavian government to study in either Moscow or Paris.

[4][5] This was part of a larger research on DNA and RNA that led him to oppose the central dogma of molecular biology promoted by Jacques Monod, head of the Pasteur Institute.

[1] After his mandatory retirement in 1988, Beljanski opened a research center in Isère, focusing on his therapeutic concepts, anticancer and antiviral remedies.

He was subsequently charged by the French Department of Health for the illicit practice of pharmacy in 1995, but died in 1998 before the case was heard in court.

[1] During this time, French President François Mitterrand received treatment for prostate cancer which included the use of Beljanski's products.

[11] In 2002, the European court of human rights ruled that the length of a second criminal investigation had been excessive and made a financial award to his widow.
