An Accidental Discovery: Sir Alexander Fleming and Penicillin

Throughout his life, Alexander Fleming dramatically changed the world's perception and knowledge of antibiotics and preservatives. Alexander Fleming was born on August 6, 1881, died on 11th March 1955 due to an unexpected heart attack. From 1903 to 1906, Alexander Fleming went to St. Mary's Hospital School of Medicine. During school, Fleming was qualified as a surgeon, but after the end of World War I, his interest turned into bacteriology. Fleming was a medical officer of the French Royal Army Medical Corporation during the First World War.

The discovery of Scottish biologist Sir Alexander Fleming by his enzyme lysozyme (1921) and the antibiotic penicillin (1928) defined a new vision for modern antibiotics. Penicillin contained in Penicillium notatum improves the treatment of bacterial infections such as syphilis, gangrene and tuberculosis. He made a tremendous contribution to medicine through his work on bacteriology, immunology and chemotherapy. His research and his military career study stimulated him to discover natural antimicrobial enzymes in 1921 when he named lysozyme. This substance is contained in tissues and secretions such as mucus, tears, egg white, but it is not effective for strong harmful bacteria. Six years later, due to successful coincidence discovery, he stumbled on penicillin

Penicillin is being developed as an antibiotic. In 1928, British bacteriologist Alexander Fleming (1881-1955) discovered the bactericidal properties of penicillin. Fleming pointed out that fungus that accidentally fell into the bacterial culture in his laboratory killed the bacteria. After identifying mold as fungus Penicillium notatum, Fleming used it to make juice and named it penicillin. After handing it to the experimental mouse, he discovered that it could kill mouse bacteria without harming healthy somatic cells. Fleming found an incredible finding, but he was unable to produce penicillin in a useful form for the doctor.

In the history of scientific innovation, the concept of accidental discovery is common. For example, Alexander Fleming incorrectly discovered penicillin in 1928, invented a microwave oven by Percy Spencer in 1945, and invented a sticky note by Spencer Silver in 1968. First use of "unexpected discovery" in English In 1754, Horace Walpole wrote a letter. In a letter to his friend Horace Man, Walpole explained his unexpected discovery of Persian fairy tale, Gianluca Vasari, who referred to the Prince of Three (lost) Bianca Cappello paintings did. Selendip he told reporters that these princes will always discover that they did not pursue through accidents and wisdom. The name comes from Serendip's old name, Sri Lanka (Ceylon), and therefore Arab merchant Sarandib. It began with Sanskrit Sijhaladvīpaḥ (Siṃhalaḥ, Sri Lanka + dvīpaḥ, Island)
