Throughout history, the curiosities of obtaining knowledge of facts that show the operation of general laws have resulted into the improvements of today’s society. Such curiosity of chemical reactions coiled in the minds of John Dalton in the atomic theory, Rosalind Franklin with genetics, and most importantly Antoine Lavoisier the father of modern chemistry. All who, worked extensively to acquire the understanding that fascinated them most, chemistry. Another chemist who sought after the same knowledge was Stanislao Cannizzaro. Studying organic chemistry Cannizzaro explained how certain elements lacked the hydrogen atom in what is know n as the Cannizzaro Reaction.
Being the youngest of ten children, Cannizzaro was born in Palermo, Sicily where his father was a magistrate and minister of police and his mother descended from Sicilian aristocracy, Anna di Benedetto. Receiving a classical education in the Palermo schools, he enrolled at the University of Palermo to study medicine. As a medical student Cannizzaro became interested in chemistry and accepted a job at the University of Pisa as a laboratory assistant for Raffaela Piria, a leading Italian chemist. Assisting with investigations of Salicin and glucosides, Cannizzaro studied chemistry for the next two years. The summer break of 1847 in an attempt to return to Palermo to finish studies a revolutionary outbreak against the Bourbons ruptured and Cannizzaro became an artillery officer. When the rebellion failed and being condemned to death Cannizzaro fled to Marseilles and soon to Paris, where he researched cyanamide and successfully synthesized cyanamide.
After a few years of exile, Cannizzaro returned to Italy and in 1851 accepted a position as professor of physics, che...

...ed Cannizzaro’s ideas. The acceptance of Avogadro’s hypothesis led Meyer and Dimitri Mendeleev to devise the periodic law in late 1860.
After the congress Cannizzaro made his way back to Palermo, where he became a council member in the new government by Garibaldi. A year later he returned to the University of Palermo as a professor of inorganic and organic chemistry. Creating a “top” research center, Palermo became the leading center for chemical studies. A decade later, he moved to Rome serving as a senator and vice president of the Italian Senate. In 1856 Cannizzaro married Henrietta Withers and had one son. During his last years Cannizzaro received honors and awards including the Copley Medal of the Royal Society in 1891. When he died he died in 1910, he impacted, provided, and left behind essential service in creating the modern science of chemistry.

After he graduated from high school, Che went to Buenos Aires University, showing interest in the medical field. His interest in the medical field was the result of his wanting to better understand his asthma; but also he had a more personal reason. His mother had developed breast cancer, and he wanted to find a cure. During his second year at college, he entered the medical college surprising his father. His father said, "I'd hoped, Ernesto, that you might be an engineer." (Franklin 10) In 1951, Che dropped his studies temporarily to go on a journey with a friend, traveling to Argentina, C...
Dmitri M. enrolled in the division of mathematical and natural sciences of the Main Pedagogical Institute of St. Petersburg, Ivan Pavlovich’s alma mater. There he worked with Aleksandr A. Voskresenkii, also known as the “Grandfather of Russian Chemistry”. In St. Petersburg, he wrote his first scientific paper, “The Analysis of Finnish Allanite and Pyroxene”, this paper led to his curiosity of building the periodic table. He graduated in 1855, where he won a gold medal for being first in his class. After a few years, Mendeleev’s thesis On Specific Volumes and The Structure of Siliceous Combinations, resulted in him being able to teach theoretical and organic chemistry at the University of St. Petersburg.
One cannot be mistaken that a cannoli is loaded with sugar, butter, and eggs like many other desserts and pastries. With all of these fatty substances, which may sound like a turnoff, this treat is very rich. Being rich is acceptable because if a cannoli is rich it resists your urge to overindulge in the treat and end up regretting the decision later on. For example, everyone gets tired of drinking water because it becomes very redundant, but because cannoli’s are rich you will only want to eat them every so often lowering your chances of getting bored with the treat. Although Cannoli’s can be very rich and hard to eat in one sitting, they can be a great fix for your sweet tooth. Instead of reaching for those Oreos or some other processed,
After graduation, he worked as a teacher at Berkeley for only a year. In 1942, he received citizenship for the United States since he was originally born in Canada. Throughout his career, he has worked as a professor in various universities. He taught at places such as Cornell University, University of Chicago, and Stanford University. Two times he was the chairman of the Chemistry Department in 1972 to 1974 and 1978 to 1979. He was also in the National Defense Research Committee while World War II was taking place.
Molina was born on March 19, 1943, in Mexico City. Molina was interested in science since a very young age that he created his own and personal chemistry lab in a bathroom at his house. Molina's aunt was a chemistry and figured out her nephew’s great interest in science. She was a key figure in his life because she helped him to perform chemistry experiments that weren't taught at his school. He completed his studies in Mexico and Germany before moving to the United States to achieve an advance degree in physical chemistry.
Galvani was born September 9, 1737, into a well-known family in Bologna. At a young age, Galvani was interested in theology. He eventually decided to pursue a career in the medical field. He studied philosophy and medicine at the University of Bologna. In the 18th century, Bologna was the center of scientific research. While at the University of Bologna, Galvani was mentored by
This chemistry book report is focus on a book called “Napoleon's buttons: How 17 molecules changed history” by Penny Le Couteur and Jay Burreson. The publisher of this book is Tarcher Putnam, the book was published in Canada on 2003 with 17 chapters (hey the number match the title of the book!) and a total of 378 pages. The genre of this book is nonfiction. “Napoleon's Buttons” contain a fascinating story of seventeen groups of molecules that have greatly changed the course of history and continuing affect the world we live in today. It also reveal the astonishing chemical connection among some unrelated events, for example: Chemistry caused New Amsterdamers to be renamed New Yorkers and one little accident of detonating cotton apron in a minor housekeeping mishap lead to the development of modern explosives and the founding of the movie industry.

Enrico Fermi was born on September 21, 1901, in Rome, Italy. He had two siblings, his sister Maria Fermi, and his brother, Giulio Fermi. His parents were Ida de Gattis and Alberto Fermi. When his brother was fourteen, Enrico’s brother, Giulio, died. This left Enrico devastated. When Enrico was a teenager, he and his friends would perform physics experiments. In 1918, He won a scholarship to Scuola Normale Superiore University in Pisa, Italy. Enrico also spent four years at the University of Pisa when he was seventeen years old. He also went to the University of Göttingen, Leiden University.
Garibaldi was born on July 4 of 1807 in Nice, France. He is the son of Domenico Garibaldi, a fishermen and coastal trader. His full name was Joseph Marie (Giuseppe Garibaldi).
