Forgotten Scientists

Our lives are very different in 2020, than they were even 30 years ago. I certainly wouldn’t be keeping in touch with you via the internet, on Wi-Fi using my mobile phone, because those things were still dreams rather than reality.

Science affects our lives- it always has done. However, unlike sports stars, actors and politicians most scientist who have global impacts on the way we live our lives get forgotten.

Who discovered the importance of handwashing?

We take it for granted, now more than ever that to stop the spread of infection we need to wash our hands.

This wasn’t always the case, bacteria, protist and viruses which cause disease are too small to be seen with out a microscope. Viruses need a special electron microscope to be seen!

So handwashing wasn’t seen to be important. If they looked clean, that was good enough!

First forgotten scientist:

Introducing on of my personal favourites………..

Ignaz Philipp Semmelweis

Nationality

Hungarian

Birth

1 July 1818

Death

13 August 1865)

Discovery

The importance of handwashing

His story

Semmelweis discovered that the number of women who died giving

birth known as "childbed fever" could be drastically cut using hand disinfection on maternity wards.

Semmelweis proposed the practice of washing hands with chlorinated lime solutions in 1847 while working in Vienna General Hospital’s

He published a book of his findings

Despite various publications of results where hand washing reduced death rate to below 1%, Semmelweis's observations conflicted with the established scientific and medical opinions of the time and his ideas were rejected by the medical community.

Continued…

Semmelweis could offer no acceptable scientific explanation for his findings, and some doctors were offended at the suggestion that they should wash their hands and mocked him for it.

In 1865, the increasingly outspoken Semmelweis supposedly suffered a nervous breakdown and was committed to an asylum by his colleague. He died a mere 14 days later, at the age of 47, after being beaten by the guards, from a infected wound on his right hand. This might have been caused by the beating.

Semmelweis's practice earned widespread acceptance only years after his death, when Louis Pasteur confirmed the germ theory, and Joseph Lister, acting on the French microbiologist's research, practiced and operated using hygienic methods, with great success.

Pasteur and Lister are remembered but very few people remember Semmelweis but his work was very important.

Now please watch the video explanation:
