"Chance favors invention only for minds prepared for discoveries by patient study and persevering efforts."
Louis Pasteur, a qualified chemist, was behind the most important scientific revolutions of the 19th century in the fields of biology, agriculture, medicine and hygiene. Beginning his research on crystallography, he soon embarked on a journey filled with discoveries which led him to develop the rabies vaccine.
Louis Pasteur’s life was filled with revolutionary discoveries and also marked by a number of events that likely fueled his desire to understand the diseases of his time. A tireless and dedicated scientist, he traveled extensively throughout France to prove his theories and solve agricultural and industrial problems caused by infectious diseases.

"Adopt a critical mind. By itself, it can neither encourage ideas nor stimulate anything great. But without it, everything is useless. It always has the last word."
THE INSTITUT PASTEUR THROUGH HISTORY
A year after the Institut Pasteur opened, Emile Roux launched the world's first ever microbiology course, entitled "Technical Microbiology". Students from all over Europe came to attend theoretical and practical training in this new scientific discipline.
The first Institut Pasteur outside France was set up by Albert Calmette in Saigon in 1891. Its role was to administer vaccines for rabies and smallpox in Indochina.
Opening of the Institut Pasteur in Antananarivo, Madagascar.
A permanent mission from the Institut Pasteur in Paris, directed by the Sergent brothers, was sent to tackle malaria in Algeria. This mission merged with an anti-rabies center to create the Institut Pasteur in Algeria. In 1960, the Institut Pasteur in Algeria launched a program to combat tuberculosis.
Opening of the Institut Pasteur in Tunis.
In April 1886, sixteen Russian patients were treated for rabies by Louis Pasteur and returned to Russia cured of the disease. Pasteur's nephew Adrien Loir traveled to Saint Petersburg to set up the first anti-rabies center outside France. In 1923, on the centenary of Louis Pasteur's birth, the Pasteur Anti-Rabies Center, associated with the Imperial Institute of Experimental Medicine, became the Institut Pasteur in Saint Petersburg. It joined the Institut Pasteur International Network in 1993.
Jean Laigret developed the yellow fever vaccine at the Institut Pasteur in Dakar. Georges Girard and Jean Robin developed a plague vaccine at the Institut Pasteur in Madagascar.
When the Institut Pasteur in French Guiana was set up, its main contributions were the development of a treatment for leprosy and epidemiology research on malaria and yellow fever.
In August 1946, the Institut Pasteur in Nha Trang (Vietnam) set up a veterinary annex in Phnom Penh, Cambodia, to produce the rinderpest vaccine. This resulted in the creation of the Institut Pasteur in Phnom Penh in December 1953. It was renamed the Institut Pasteur in Cambodia in 1958 and shifted its focus to human biology and diseases.
The Institut Pasteur in New Caledonia was set up in 1954. Following a dengue outbreak which affected 40% of the population, an Institut Pasteur mission in Nouméa identified the viral type and paved the way for the creation of an arbovirology and entomology unit in 1974.
The Institut Pasteur in Bangui, which opened in 1961, is a state-approved organization in the Central African Republic. It mainly focuses on research into arboviruses (arthropod-borne viruses).
The Institut Pasteur in Côte d'Ivoire, which opened on July 27, 1972, is involved in the development of rapid diagnostic techniques for arboviruses and enteroviruses and in microbial monitoring.
In 1989, the institutes formalized their membership of the Pasteurian community, as well as their resulting rights and obligations, by adopting a General Declaration of Scientific Cooperation. The declaration was signed by each director and marked the official launch of the Institut Pasteur International Network. Ever since, despite the closure of some institutes (owing to major changes in local policy), the number of institutes has continued to grow.
The Hong Kong University – Pasteur Research Pole, created in 1999 and officially opened in 2000, focuses its research on viruses that represent a risk for public health in the region. It is currently investigating emerging and re-emerging infectious diseases in China, including SARS, influenza, AIDS, dengue and hepatitis C.
The CERMES (Center for Medical and Health Research in Niger), which joined the International Network in 2002 with the new status of associate institute, conducts research on bacterial meningitis, malaria and HIV/AIDS.
In Brussels, an institute founded in 1901 by Jules Bordet became a member of the Institut Pasteur International Network. In 2008, this institute was integrated into the Directorate of Communicable and Infectious Diseases of the Scientific Institute of Public Health (WIV-ISP), with the entire institute becoming a corresponding member of the International Network.
The Institut Pasteur in Montevideo, Uruguay, the result of trilateral cooperation between the French and Uruguayan governments and the Institut Pasteur, joined the International Network in June.
The Institut Pasteur in Laos was officially opened in Vientiane in January 2012, becoming the 32nd institute in the Institut Pasteur International Network. The aim of this new research center for infectious and parasitic diseases is to reduce the risks of pandemic outbreaks in Southeast Asia, where such diseases are rife.
On November 11, 2016, in Conakry, the President of the Republic of Guinea, His Excellency Professor Alpha Condé, laid the first stone of the Institut Pasteur in Guinea at a ceremony attended by the French Minister of Foreign Affairs and International Development, Jean-Marc Ayrault. The decision to set up an Institut Pasteur in Guinea was made in 2014 in response to the Ebola crisis. It reflects the joint determination of the French and Guinean Presidents to tackle emerging outbreaks on a long-term basis. This led to the signing of a memorandum of understanding between the Republic of Guinea and the Institut Pasteur in September 2015.
