Alexandre Emile Jean Yersin (22 September 1863 – 1 March 1943) was a Swiss-French physician and bacteriologist. He is remembered as the co-discoverer of the bacillus responsible for the bubonic plague or pest, which was later named in his honour: Yersinia pestis. Another bacteriologist, the Japanese physician Kitasato Shibasaburō, is often credited with independently identifying the bacterium a few days earlier. Yersin also demonstrated for the first time that the same bacillus was present in the rodent as well as in the human disease, thus underlining the possible means of transmission.

Early life and education

Yersin was born in 1863 in

canton of Vaud, Switzerland, as the posthumous son of Jean-Alexandre-Marc Yersin from his wife Fanny-Isaline-Emilie Moschell.[1] From 1883 to 1884 he studied medicine at Lausanne, followed by Marburg, and Paris
(1884–1886).

Career

In 1886, Yersin entered

Emile Roux, and participated in the development of the anti-rabies serum. In 1888 he received his doctorate with a dissertation titled Étude sur le Développement du Tubercule Expérimental [Study on the Development of Experimental Tubercule] and spent two months with Robert Koch
in Germany.

He joined the recently created Pasteur Institute in 1889 as Roux's collaborator and discovered with him the diphtheric toxin, produced by the Corynebacterium diphtheriae bacillus.

In order to practice medicine in France, Yersin applied for and obtained French nationality in 1888. Soon afterwards (1890), he left for

Saigon-Manila line and then on the Saigon-Haiphong line. He participated in one of the Auguste Pavie missions. In 1894 Yersin was sent by request of the French government and the Pasteur Institute to Hong Kong, to investigate the plague
happening there.

There, in a small hut since he was denied access to British hospitals at his arrival,

Emile Duclaux, in a classic paper titled "La peste bubonique à Hong-Kong".[6]

From 1895 to 1897, Yersin further pursued his studies on the bubonic plague. In 1895 he returned to the Institute Pasteur in Paris and with Émile Roux,

Bombay, India, in 1897, with disappointing results. Having decided to stay in his country of adoption, he participated actively in the creation of the Medical School of Hanoi
in 1902, and was its first director, until 1904.

Yersin tried his hand at

Hon Ba in 1915, where he tried to acclimatize the quinine tree (Cinchona ledgeriana), which was imported from the Andes in South America by the Spaniards, and which produced the first known effective remedy for preventing and treating malaria
, a disease which prevails in Southeast Asia to this day.

Alexandre Yersin is well remembered in Vietnam, where he was affectionately called Ông Năm (Mr Nam/Fifth) by the people.

On 8 January 1902, Yersin was accredited to be the first Headmaster of

In 1934 he was nominated honorary director of Pasteur Institute and a member of its Board of Administration.

Death and legacy in Vietnam

He died at his home in Nha Trang, in 1943.

Following the country's independence, streets named in his honor kept their designation and his tomb in Suoi Dau was graced by a pagoda where rites are performed in his worship.

Yersin Market in Ho Chi Minh City was named after him.[8] His house in Nha Trang is now the Yersin Museum
, and the epitaph on his tombstone describes him as a "Benefactor and humanist, venerated by the Vietnamese people".

In Hanoi, the Lycée français Alexandre Yersin, a French international school was named after him.

A private university founded in 2004 in Da Lat was named "Yersin University" in his honour [Trường Đại Học Yersin Đà Lạt].[9]

Miscellaneous

Dr Yersin was credited with founding the site for the new town of Da Lat in 1893. Because of the high altitude and European-like climate, Da Lat became an R&R spot for French officers. There was a high school named after him which was built in the 1920s, the Lycée Yersin, aka Grand Lycée (grade 6 to 12), the Petit Lycée (elementary to grade 5), and a university named after him which was built in the 2000s.

While in Hong Kong, Yersin was helped in his research by an Italian priest of the PIME order named Bernardo Vigano. He provided cadavers and assisted with his quest to find a remedy for the plague.
