P1.Explain the role of scientists in the development of current understanding of microbiology:-

As part of this assignment I am asked to choose three scientists that as a result of their discoveries and inventions in their day, still have an influence on today’s understanding of microbiology. The three microbiologists I have chosen to discuss are Anton van Leeuwenhoek, Louis Pasteur and Robert Hooke. In order to answer this question I will use resources such as the internet and books as they will have the most relevant and up to date information to back up my answers. I will ensure to reference throughout to use as evidence.

Anton Van Leeuwenhoek was a Dutch scientist born 24th October 1632. He was known as the father of microbiology. Leeuwenhoek was self-taught and had never obtained a degree. He is famously acknowledged for improving the microscope and made over 500. Today only as many as 9 of Leeuwenhoek’s microscopes are still in existence.   He had great interest and passion for the microscope. It was with hard dedication that he was able to produce lenses that could magnify over 200 times and present a clear picture of his findings.

Leeuwenhoek was the first ever scientist to give a detailed explanation of red blood cells and human spermatozoa or to explore single-celled bacteria and protozoa. In 1683 he scraped some plaque from his teeth, examined it under one of his microscopes, and found living bacteria.   Leeuwenhoek later examined a drop of rainwater and noticed it contained tiny creatures he called "animalicules".

Without Leeuwenhoek’s improvement of microscopes scientists today may have not made   such important discoveries that have undoubtedly made substantial improvements to the world of medicine.

Louis Pasteur was a biologist born December 1862 and originated from France. Pasteur demonstrated that microorganisms such as bacteria were accountable for fermenting the likes of wine, beer and milk. He then invented a process where...
