Américo Garibaldi Ghersi was a Peruvian scientist known mainly for his extensive research and contributions in the study of cancer and malaria.

He presented a new theory on endocrine allergy to the Académie des Sciences, which was published in its bulletin.

Early life and education

Américo Garibaldi Ghersi was born on January 15th 1893, in Ilo, a port city located in the department of Moquegua in southern Peru, to Gaetano Garibaldi, an Italian merchant, and Rosa Ghersi.

He completed his primary and secondary education in Lima, Peru. He enrolled at the Faculty of Science at the National University of San Marcos, completing his studies there in 1909. After this, he paused his studies and traveled to France in 1913.

That same year, in France, he studied at the Sorbonne University in Paris. In 1919, Garibaldi entered the Faculty of Medicine in Paris, from where he graduated as a Bachelor of Medicine in 1923, with the thesis "Thyroid insufficiency and immunity", which won him the faculty's thesis medal.

Career

In 1923, Garibaldi began to work at the laboratory of experimental pathology of Georges Henri Roger, dean of the Faculty of Medicine; the experimental physiology research laboratory of professor Charles Richet; and the laboratory of experimental biology at the Collège de France.

In 1925, upon returning to Peru, Garibaldi revalidated his academic title at the Faculty of Medicine "San Fernando" at the National University of San Marcos. Where he was appointed head of Pharmacology and Pathophysiology. Garibaldi introduced a new procedure for the serological diagnosis of pregnancy and cancer, which was presented at the Third Pan-American Scientific Congress, and earned him his Doctorate in 1931.

Between 1932 and 1934, he traveled to Europe to study malaria, working at the Institute of Exotic Pathology in Paris and the Malariology Institute in Rome. During this period, he developed a new method for malaria treatment, published in 1935.

In 1936, he was commissioned by the Peruvian government to investigate cancer in the United States. He worked in New York under the auspices of the Rockefeller Institute, where he discovered a vaccine capable of immunizing against certain cancerous tumors. His achievements earned him membership at Fordham University, making him the first oncologist to be inducted into the institution. To further his cancer research, the Westinghouse company provided him with a specially designed radiotherapy apparatus.

Ghersi passed away in New York on December 21, 1938, at the age of 45, while working to perfect the anticancer vaccine he had discovered.
