Marek Maria Pienkowski (born 8 September 1945) is a Polish-American medical researcher and clinician focused on broad aspects of immunological diagnosis and treatment.
He collaborated in important discoveries related to immunology, viral oncogenes, genetic engineering, and cloning and has implemented desensitization treatments for allergic disorders based on this research into his clinical practice.
He is also recognized as a cultural ambassador for the propagation of artistic, scientific, and business dialogue between the U.S.
and Poland and has been appointed by the government of Poland and accredited by the U.S.
State Department as an Honorary Consul.
He authored the biographical memoir Iron or Steel: A Memoir on Living Dreams.
Information conveyed in the book has been shown to be factual falsehoods.
For example, in the book, Marek recounted on his departure from Poland in 1974 as an impulsive decision without time to plan.
It has been revealed that there was much planning involved over a period of time with motives that have nothing to do with communism, but rather issues among his nuclear family.
