Ignaz Semmelweis (1818-1865), the antiseptic pioneer
by getting people to wash their hands
he worked in Vienna general hospital ;)
Ignaz Semmelweis was a Hungarian physician who is known for promoting the importance of handwashing in medical settings to prevent the spread of infections, particularly childbed fever. His work helped pave the way for the germ theory of disease and was instrumental in improving hygiene practices in healthcare.
Ignaz Semmeilweiss changed the way Doctors work by discovering that different types of bacteria that spread can cause diseases which in the ninteenth century, were killing people or making them very ill. This changed the way Doctors worked by washing their hands very often and using new medicines to fight off unknown bacteria.
Robert Koch did not develop antisepsis; he is known for his work in germ theory and his role in establishing the techniques of bacteriology. Antisepsis, the practice of killing or inhibiting microbes on living tissue, was developed by Joseph Lister and Ignaz Semmelweis.
Semmelweis worked in the obstetrics clinic at the General Hospital in Vienna, Austria, in the mid-19th century.
Relevant is a big word that encompasses things like "Science" "Belief" and "Society"The one word answer to this huge subject is YES
Henri Fayol's principal is relevant in work today because some of the principals are still in use. Those are division of work, also known as specialization, and authority.
Yes, Albert Bandura's research on social learning theory and self-efficacy continues to be relevant today. His work has influenced fields such as education, psychology, and behavior modification. Bandura's concepts are still widely used to understand how individuals learn and develop beliefs about their abilities.
Why would you want to waste your money, just make one. Its not like they really work anyway. Buy a butterfly net and hang yourself with it in your dreams. That may all be true but history is full of instances where this kind of thinking turned out to be false. Dr. Semmelweis (Ignaz Philipp Semmelweis July 1, 1818 - August 13, 1865) was run out of the medical profession for suggesting that doctors should wash their hands for example. There are some true artists making dream catchers. I personally could not do anything nearly as well. In addition native American artists have access to legally and sustainably harvested materials that I do not such as naturally shed antlers, naturally shed eagle feathers and similar.
Art should be eternal. A piece of art which is about the past and has no relation to today, is not relevant.
