Louis Pasteur

This 19th-century machine was used to pasteurize milk bottles. Louis Pasteur battled bacteria to save thousands of lives, placing health and hygiene at the forefront of modern science. Louis Pasteur MASTERMIND of microbiology Patients infected with rabies queued for treatment.

Pasteurization

In the early 1860s, Pasteur’s research showed that heating a liquid to 55°C (131°F) killed bacteria without changing the liquid’s taste. This process, later called pasteurization, was adopted by the dairy industry; milk is PURIFIED by pasteurization before it is ready for sale.

What came after…

Fresh findings In the early 19th century, people believed infections appeared from nowhere. Born in 1822, French chemistry professor Louis Pasteur EXAMINED different types of infections. He proved that they are caused by germs, including some kinds of bacteria. Carbolic acid spray Did you know? Established in 1887 by the great scientist himself, the Pasteur Institute in France is still at the forefront in the battle against infectious diseases. Surgical tools used in the 19th century

antiseptics kill germs in order to help mend wounds. Antiseptic sprays were first used in 1865, making surgical operations cleaner and safer than ever before. In 1886, German surgeon Ernst von Bergmann introduced the technique to sterilize

surgical instruments and

dressings with steam.

Meister was the first person to receive the rabies vaccine. In 1865, Pasteur investigated why disease was destroying silkworm cocoons. He found GERMS were causing the infection. This proved diseases came from harmful types of bacteria and other microorganisms invading living things.

By the way… I always loved to draw and paint in my spare time.

Rabies vaccination

A vaccine is an injection that gives a patient a low dosage of a disease so the body recognizes how to fight it effectively. In 1885, Pasteur created a VACCINE FOR RABIES – a deadly disease spread from infected animals to humans. He performed the first rabies vaccination on nine-year-old Joseph Meister.

The boy, who had recently been bitten by an infected dog, recovered fully.

The vaccine for smAllpox, originally developed by English scientist Edward Jenner, was so successful that in 1980, the disease was declared extinct. Pasteur’s pioneering work changed medical science forever. Vaccines have since been developed for many serious diseases that used to be How he changed the world common, saving more than two million lives every year.

Strand of DNA

In the 1980s, scientists discovered a safer way of making vaccines that didn’t involve infection with a virus; they took DNA from the disease-causing virus and used it to make a vaccine.
