His father, Hermann Meyer, a Swiss polytechnics engineer specializing in agronomy, became a fazendeiro (large plantation farmer), first in Argentina, in the early 1930s, then in Brazil in 1954.

This official mission led him into the heart of the Amazonian rain-forest for the first time,[3] where he undertook an exhaustive case study about the different forms of graphic representations of the written language used by the Amerindians in their pictographs, ideograms, petroglyphs and body paintings (e.g. Genipapo – Genipa americana, Urucu – Bixa orellana), obtained using plant pigments,[4] where he discovered the power of their active ingredients.

This association allowed him to fight for the transformation of the Amazonian biodiversity and medicinal plants into a truly genuine pharmacology benefiting both Amazonia and the Western world.

It is in this context that, in 1994, he coordinated on Brazilian territory – after a due hand-over by the French Ambassador in Brasília – the first Ministerial "mission for biotechnology to valorize biodiversity" ever to be organized between France and the State of Amazonas.

In 1994, Meyer appeared as a special delegate from Brazil to the UNESCO's World Symposium on Literacy[12] in order to present his new approach merging linguistic abilities and biodiversity know how.

[15] Meyer is currently adapting a process for the bio-production of active ingredients contained in medicinal plants to the needs and abilities of the Índios, enabling them to manage the production of these pharmaceuticals and ensuring them economic autonomy and self-sustainable development.

[18] He is now focusing his work on the goal-achievement methodology of his original research and development program to ensure a functional and active link between theÍndios ancestral knowledge and Scientist's advanced biotechnology.

[19] For more than three decades, Meyer's work has been published by leading international scientific journals, magazines and books, as well as progressively in the mainstream press, as can be seen in "Selected Publications", up to recent articles.

[25] In September 2017, the Herb'Içana project was awarded and received special homage from the Giants of Ecology Institute (Brazil) for its relevance, and was appointed as a solution for the wound no 7, "loss of biological diversity which affects the lives of all living things", described in the book "12 Feridas Ambientais do Planeta" ["12 Environmental Wounds of the Planet"], coordinated by Gustavo Siqueira and Prof. Dr. Joel Dias da Silva, Brazil, 2017.

[31][32] Meyer was made an honorary citizen of the city of Manaus, capital of the State of Amazonas, and was granted a gold medal by its legislative chamber, in recognition of the 30 years of services he provided for the defense of the rich biodiversity of Amazonia and the development of the Herb'Içana project.
