Fleming alexander biography
Alexander Fleming was a Scottish physician and microbiologist who is credited with discovering penicillin, one of the most important antibiotics in the world. He was born on August 6, 1881 in Lochfield, Scotland and was the youngest of four children.
Fleming received his education at the Royal Polytechnic Institution in Edinburgh and later went on to study medicine at St. Mary's Hospital Medical School in London. After completing his studies, he worked as a bacteriologist at St. Mary's Hospital and later became a professor at the University of London.
In 1928, Fleming made his most famous discovery while working in his laboratory at St. Mary's Hospital. He noticed that a culture of bacteria he was studying had been contaminated with a mold, and that the mold had killed the bacteria. He realized that this mold had the potential to be developed into a medicine that could kill bacteria in the human body and began researching its use as an antibiotic.
Over the next few years, Fleming worked to purify and isolate the active ingredient in the mold, which he named penicillin. He faced many challenges in his research, including the fact that penicillin was very difficult to produce in large quantities. However, he persevered and eventually succeeded in isolating a form of penicillin that was effective against a wide range of bacteria.
In 1945, Fleming was awarded the Nobel Prize in Physiology or Medicine for his discovery of penicillin, along with Howard Walter Florey and Ernst Boris Chain, who had helped him to develop and mass-produce the drug.
Fleming's discovery of penicillin has had a profound impact on the field of medicine and has saved countless lives. It is one of the most widely used antibiotics in the world and has helped to treat and prevent a variety of infections.
Fleming died on March 11, 1955, at the age of 73, but his legacy lives on as one of the most significant figures in the history of medicine.

Fleming bore these disappointments stoically, but they did not alter his views or deter him from continuing his investigation of penicillin. In reality, the process of taking penicillin and turning it from a simple mold into a practical medicine was long and difficult and involved a lot of work from many different scientists. In his Nobel lecture on 11 December 1945 he briefly mentioned lysozyme, saying, "Penicillin was not the first antibiotic I happened to discover. While at the Potsdam Conference on postwar settlement in July 1945, U. They started their work on penicillin in 1939, with the main goal being to isolate and stabilize enough of it to be usable on humans. It happened when Fleming dropped a drop of mucus from his nose on a culture of bacteria.
The Penicillin Committee was created on 5 April 1943. Fleming bore these disappointments stoically, but they did not alter his views or deter him from continuing his investigation of penicillin.

For a while, it looked like manufacturing large quantities of penicillin would have been nigh-impossible. It was later corrected as P. He grouped up all of his Petri dishes that contained bacterial colonies and left them near an open window in his lab. Antiseptics, which were used at the time to treat infected wounds, he observed, often worsened the injuries. But I suppose that was exactly what I did.
