TS. Alexandre Yersin born in 1863 in the State of Vaud, Switzerland. At the age of 20, he studied medicine in Lausanne (Switzerland), then continued to study in Marbourg (Germany) and graduated from the University of Paris (France) with a doctorate in medicine. Since 1886, Yersin worked at the Pasteur Institute and collaborated with Dr. Roux to find out the toxin of the diphtheria bacteria. In 1889, Yersin naturalized French. Yersin- the world-famous doctor thanks to the discovery of bacteria that cause plague. A bright future is opening up Young Yersin . However, in addition to his passion for medicine, Yersin has a desire to explore nature. To fulfill his dream of exploring strange lands, he would like to be a doctor on a transport ship floating at sea. In 1892, he went to Nha Trang, Vietnam. The tropical climate is full of mysteries and attractions that make the decision to live, work and stick with this land. Here, he made expeditions to discover new lands. Thanks to these trips, Yersin found Lang Biang Plateau. That was January 1893, he made an expedition that lasted for nearly 7 months. After crossing the rugged mountains and ethnic minority villages, in June 1893 Yersin discovered Lam Vien Plateau (Lang Biang Plateau), 1,500 meters high, today Da Lat city. Yersin wrote in his notebook: “The impression is so profound. Out of the pine forest, I saw right in front of the vast, bare plateau, like the sea was rolling in green waves. The Lam Mountains. Vien with 3 peaks of 2,000 meters, rising from the northwest horizon, creates a majestic backdrop that enhances the magnificence of this region “. In 1897, it was he who proposed to the Governor-General of Indochina, Paul Dumer, to choose this place as the site for the construction of the sanatorium. Then, by a trip to the plateau with the Governor-General of Indochina, he took part in deciding to establish a nursing station on Lang Biang Plateau – the forerunner of Da Lat city later. The first person to find the bacteria that cause the plague In 1894, while preparing to make the next expedition, at the request of the French Government and the Pasteur Institute, Yersin traveled to Hong Kong to study the plague. Here he saw dead bodies of plague dead in the streets, among puddles, in gardens, on moored boats. Yersin has spent most of his life in Vietnam. When Yersin discovered that his colleagues were looking for the plague bacteria in the blood, Yersin said that this is not the right way. According to Yersin, the bacteria must be found in the lymph nodes. With the help of Vigano, an Italian living in Hong Kong, Yersin works in a straw-covered bamboo shack. In order to get the corpses for experimentation, he had to pay money to British sailors who were supposed to bury the bodies. Thanks to that, Yersin was able to enter the body cellar several hours before the body was taken to the cemetery. He had to remove the lime coating the corpse, cut the lymph nodes himself from the corpse and bring it to his laboratory. The microscope shows a multitude of homogeneous images of stick-shaped, two-headed, stick-shaped bacteria. Yersin injected the bacteria into the mouse, twenty-four hours after the mouse died. Other test animals die from two to six days and in cadavers full of lymph nodes. Over a period of seven days, Yersin found the plague bacteria. He sent to the Pasteur Paris Institute a number of fully filled test tubes taken from the sick lymph nodes. When the plague in Hong Kong has calmed down, Yersin returned to France to work with colleagues on the vaccine to prevent it, and the sera (sérum) to treat the plague. When the serum production was completed, Yersin asked to return to Nha Trang to set up a laboratory and build a horse farm in Suoi Dau to produce a lot of serum to prevent patients in neighboring countries. In 1975, the Tenth World Congress of Biology decided to name the plague bacterium “Yersinia-Pestis”. Scientists said that Dr. Yersin was the benefactor of humanity when it was able to prevent the plague at that time. Add more imprints In 1902 – 1904, at the request of Governor-General of Indochina Paul Dumer, Yersin went to Hanoi to establish and run the Indochina Medical and Pharmaceutical School in Hanoi – the first medical training facility of the Indochinese peninsula. built according to the model of the West. Besides medicine, Yersin is passionate about exploring new lands During those difficult early years, Yersin worked actively to found the Medical and Pharmaceutical University and became the first principal of the University (a member of Indochina University in 1906, later to become the University of Indochina). Ha Noi medical university). With his contributions and dedication to the field of medicine, in 1904, Yersin was appointed as a representative of Pasteur Paris Institute in Indochina and Director of Pasteur Institute Saigon and Nha Trang. He also holds many important positions in the health sector. Not only contributing in the medical field, he also has many contributions in the agricultural field. He was the first to import rubber trees from Brazil to plant in Vietnam. Not only importing trees, he also pays special attention to the methods of planting, exploiting and processing rubber to have the highest efficiency. He set up an agrochemical laboratory. Here, the methods of breeding, tapping and coagulating rubber have been studied in a systematic way. Thanks to that, rubber growers in Indochina in the past no longer had to struggle as before. Yersin breathed his last in early 1943. According to his wishes, when he was buried, he was placed on his stomach, his head turned to the sea so that he forever embraced his second home land.
