Ernest Duchesne
Ernest Duchesne (30 May 1874 – 12 April 1912) was a French physician who noted that certain molds kill bacteria. He made this discovery 32 years before Alexander Fleming discovered the antibiotic properties of penicillin, a substance derived from those molds, but his research went unnoticed. Life and work Duchesne entered ''l'Ecole du Service de Santé Militaire de Lyon'' (the Military Health Service School of Lyons) in 1894.

Scientists From Paris
A scientist is a person who conducts scientific research to advance knowledge in an area of the natural sciences. In classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science. Though Thales (circa 624-545 BC) was arguably the first scientist for describing how cosmic events may be seen as natural, not necessarily caused by gods,Frank N. Magill''The Ancient World: Dictionary of World Biography'', Volume 1 Routledge, 2003 it was not until the 19th century that the term ''scientist'' came into regular use after it was coined by the theologian, philosopher, and historian of science William Whewell in 1833. In modern times, many scientists have advanced degrees in an area of science and pursue careers in various sectors of the economy such as academia, industry, government, and nonprofit environments.''''

History Of Penicillin
The history of penicillin follows a number of observations and discoveries of apparent evidence of antibiotic activity of the mould ''Penicillium'' that led to the development of penicillins that became the most widely used antibiotics. Following the identification of ''Penicillium rubens'' as the source of the compound in 1928 and with the production of pure compound in 1942, penicillin became the first naturally derived antibiotic. There are anecdotes about ancient societies using moulds to treat infections, and in the following centuries many people observed the inhibition of bacterial growth by various moulds. However, it is unknown if the species involved were ''Penicillium'' species or if the antimicrobial substances produced were penicillin. While working at St Mary's Hospital in London, Scottish physician Alexander Fleming was the first to experimentally discover that a ''Penicillium'' mould secretes an antibacterial substance, and the first to concentrate the active sub ...
