Alexander Fleming is a prominent Scottish scientist, who worked in the spheres of bacteriology, immunology, and biology. A. Fleming obtained solid educational background, graduating from the Kilmarnock Academy and Royal Polytechnic Institution. After finishing his studies, young A. Fleming started working in the vaccine therapy and immunology. His scientific findings such as the discovery of enzyme lysozyme and the antibiotic substance brought him numerous awards and global recognition. In 1945, A. Fleming won the Nobel Prize in Physiology or Medicine for his significant contribution to the treatment of infectious diseases and invention of the antibiotic substance known as penicillin. During the World War II, Alexander Fleming paid a great attention to the invention of anti-bacterial chemical, which could have protected the human organism from the harmful effects of antiseptics. It was estimated that bacteria and infections killer not so many soldiers as the antiseptic substances di...
Charles Darwin is an English naturalist, whose scientific carrier concerns the evolutionary theories and discoveries of the origin of all living beings. Ch. Darwin is best known for his evolutionary theory, which states that all species have undergone a long period of evolution, which started from the common ancestor. Besides, Charles Darwin developed the basic principles of evolution and interpretation of species’ survival and cooperation within the eco-systems. To a great extent, Ch. Darwin’s findings explain the origin of humans as well as physiological and psychological mechanisms of people and animals. Charles Darwin obtained his education at the University of Edinburgh and Oxford University. His field of interest comprised of the evolutionary studies of humans and other living beings. He suggested his interpretation of the evolution, which stated that all species derive from a common ancestor. In the process of evolution, the survival of certain species is explained by the pro...
As it has been already mentioned, the investigations of these scientists have changed the course of the human history and development of sciences. The invention of antibiotics allowed medicine to prevent human deaths from numerous infections and create new effective tools of overcoming serious diseases. Moreover, A. Fleming’s discoveries enable humans to obtain the needed substances and utilize them for the sake of human health and welfare.
The scientific careers of Alexander Fleming and Charles Darwin have many common features. Thus, both scientists were innovators in the fields of their activities as both the invention of penicillin and evolutionary theory of species were the new discoveries, which had not been made or analyzed before. Secondly, both Fleming and Darwin changed the traditional perception of medicine and biology on the account of their progressive views and discoveries. The findings of both researchers provided new visions and ideas for the further development of science.

Born in Lochfield, Ayrshire, Scotland, Fleming was the seventh of eight surviving children in a farm family. His father died when he was seven years old, leaving his mother to manage the farm with her eldest stepson. Fleming, having acquired a good basic education in local schools, followed a stepbrother, already a practicing physician, to London when he was 13. He spent his teenaged years attending classes at Regent Street Polytechnic, working as a shipping clerk, and serving briefly in the army during the Boer War (1899–1902), although he did not see combat. Then in 1901 he won a scholarship to St. Mary’s Hospital Medical School in Paddington, London, which remained his professional home for the rest of his life.
Fleming accepted a post as a medical bacteriologist at St. Mary’s after completing his studies, and in 1906 he joined the staff of the Inoculation Department under the direction of Sir Almroth Wright. Wright strongly believed in strengthening the body’s own immune system through vaccine therapy, not by chemotherapy—the introduction of external chemical agents (see Paul Ehrlich). Nonetheless, he turned over to Fleming samples of a new drug, Salvarsan, synthesized by Paul Ehrlich and colleagues for treating syphilis. Fleming’s experience administering the drug to patients was positive, and thereafter he maintained a small but lucrative practice administering Salvarsan to wealthy patients suffering from syphilis. During World War I, Fleming worked at a special wound-research laboratory in Boulogne, France, headed by Wright. There he began research that produced results more in keeping with Wright’s thinking. He was able to demonstrate that then commonly used chemical antiseptics like c...
Fleming’s legendary discovery of penicillin occurred in 1928, while he was investigating staphylococcus, a common type of bacteria that causes boils and can also cause disastrous infections in patients with weakened immune systems. Before Fleming left for a two-week vacation, a petri dish containing a staphylococcus culture was left on a lab bench and never placed in the incubator as intended. Somehow, in preparing the culture, a Penicilliummold spore had been accidentally introduced into the medium—perhaps coming in through a window, or more likely floating up a stairwell from the lab below where various molds were being cultured. The temperature conditions that prevailed during Fleming’s absence permitted both the bacteria and the mold spores to grow; had the incubator been used, only the bacteria could have grown. Fleming’s laboratory notebooks are sketchy, and his subsequent accounts of the discovery are contradictory. The evidence of the first culture, which he photographed, in...
Alexander Fleming, in full Sir Alexander Fleming, (born August 6, 1881, Lochfield Farm, Darvel, Ayrshire, Scotland—died March 11, 1955, London, England), Scottish bacteriologist best known for his discovery of penicillin. Fleming had a genius for technical ingenuity and original observation.
May 17, 2014 · Sir Alexander Fleming knew for a long time that there was no reason for the soldiers who fought in World War I to be dying from terrible diseases that they contracted out on the front lines. Born in Scotland in the late 19th century, he wrote numerous papers about immunology, chemotherapy, and bacteriology up until the time of his death.

What sort of contribution did Alexander Fleming made to microbiology? He has discovered penicillin, the first form of antibiotics in 1928. It was an accidental discovery when he grew cultures of bacteria on petri dishes in the hospital where he worked.
Alexander Fleming discovered penicillin, whose use as an antibiotic has saved untold millions of lives. Less well-known is that before making this world-changing discovery, he had already made significant life-saving contributions to medical science.
