Louis Pasteur – Chemistry and Microbiology Scientist

29-Nov-09

louis pasteurLouis Pasteur was a French chemist and microbiologist born in Dole. He is best known for his remarkable breakthroughs in the causes and preventions of disease. His discoveries reduced mortality from puerperal fever, and he created the first vaccine for rabies. His experiments supported the germ theory of disease. He was best known to the general public for inventing a method to stop milk and wine from causing sickness, a process that came to be called pasteurization. He is regarded as one of the three main founders of microbiology, together with Ferdinand Cohn and Robert Koch. Pasteur also made many discoveries in the field of chemistry, most notably the molecular basis for the asymmetry of certain crystals. His body lies beneath the Institute Pasteur in Paris in a spectacular vault covered in depictions of his accomplishments in Byzantine mosaics.

Early life and biography

Louis Pasteur was born on December 27, 1822, in Dole in the Jura region of France, into the family of a poor tanner. He grew up in the nearby town of Arbois, where he later had his house and laboratory, these are now a Pasteur museum. He gained degrees in Letters and in Mathematical Sciences before entering the École Normale Supérieure, an elite college. After serving briefly as professor of physics at Dijon Lycée in 1848, he became professor of chemistry at the University of Strasbourg, where he met and courted Marie Laurent, daughter of the university’s rector, in 1849. They were married on May 29, 1849, and together had five children, only two of whom survived to adulthood, two died of typhoid and one of a brain tumor. These personal tragedies inspired Pasteur to try to find cures for diseases such as typhoid.

Anita B. Roberts - Biologist Scientist

She has achieved international acclaim for her work in growth factor research, having discovered and characterized, together with Dr Sporn, the cytokine transforming growth factor-β (TGF-β).

Anita B. Roberts (Born: April 3, 1942 ; Died: May 26, 2006) was a molecular biologist who made pioneering observations of a protein, TGF-β, that is critical in healing wounds and bone fractures and that has a dual role in blocking or stimulating cancers. Roberts was the 49th most-cited scientist in the world and the second most-cited female scientist as of 2005.

Roberts was born in Pittsburgh, Pennsylvania, where she grew up. She attended Oberlin College and earned her doctorate in biochemistry from the University of Wisconsin-Madison in 1968. After postdoctoral work at Harvard Medical School, Dr. Roberts joined the National Cancer Institute in 1976. From 1995 to 2004, she served as Chief of the institute’s, and continued her research until her death in 2006.

In the early-1980s, Dr. Roberts and her colleagues at the National Cancer Institute, part of the National Institutes of Health in Bethesda, Maryland began to experiment with the protein, called TGF-β, short for transforming growth factor beta.
