Dimitri Mendeleev (#59)

Background

Dimitri Ivanovich Mendeleev was born on February 8, 1834 near Tobolsk in Siberia. There is no consensus on how many siblings Mendeleev had, but all sources agree that the number was at least eleven. Dimitri's father supported the family by teaching fine arts, politics, and philosophy, but after some time, Mendeleev's father became blind and lost his teaching position. Mendeleev's mother was forced to restart her family's abandoned glass factory, but when he was thirteen, Mendeleev's father died and the glass factory was destroyed in a fire, so Mendeleev was sent to study at the Gymnasium in Tobolsk.

In 1850, Mendeleev's family moved to St. Petersburg and Mendeleev began to attend the Main Pedagogical Institute. After graduation in 1855, Mendeleev contracted tuberculosis and moved to the Crimean Peninsula to recover his health. While away, Mendeleev became the science master of the Simferopol gymnasium No. 1, but returned to St. Petersburg in 1857.

On April 27, 1862, Mendeleev married Feozva Nikitichna Lescheva with whom he was married to until 1882, when he became obsessed with Anna Ivanova Popova. Mendeleev divorced Lescheva and married Popova.

Career in Science

Mendeleev studied several areas in science including the capillarity of liquids and the science behind spectroscopes. In 1864, Mendeleev became a professor at Saint Petersburg Technological Institute and at Saint Petersburg State University. In 1865, Mendeleev became a Doctor of Science and achieved tenure two years later. Mendeleev is widely credited as being the man who helped Saint Petersburg become an internationally recognized center of chemistry. He is also said to have been the man who brought the metric system to Russia.

In 1869, Mendeleev was writing a book on chemistry and, while doing so, organized a table of  the 56 known elements based on atomic mass, weight, and chemical properties. This was the first periodic table ever created. Mendeleev also predicted the existence of three chemicals that would make his table make more sense. These predicted elements did exist as gallium, germanium, and scandium. The periodic table was widely expanded upon as more knowledge came in concerning the elements and their properties.

Mendeleev went on to formulate new state standards for the production of vodka in 1893 while working as the Director of the Bureau of Weights and Measures. He also helped to investigate the properties of petroleum and found the first oil refinery in Russia. He was also nominated several times for the Nobel Prize in Chemistry, but was not chosen for the award due to Svante Arrhenius, who discouraged his selection due to Mendeleev's critiques on Arrhenius's work.

The End

Before he died, Mendeleev received the Copley Medal from the Royal Society of London. He also was elected as a member of the Royal Swedish Academy of Science. Mendeleev died in 1907 at the age of 72 in Saint Petersburg due to influenza. Mendeleev has been honored by having both a crater on the moon and an element named after him. Mendeleev is on our list because he developed a table that is known world wide and can be found in almost every university and high school science classroom. Also, anyone with a moon crater named after them is pretty awesome.

Jack the Ripper (#62, August 31st)

Background

In the mid-1800s, many immigrants were flooding into London, mainly into London's East End. Irish immigrants were coming from the West, and Jewish Immigrants were coming from the East. The sudden jump in population led to worsening of conditions in London. On April 3rd, 1888, the first of eleven "Whitechapel Murders" took place in London's East End.

Murders

During the investigation process of these eleven murders, at least five are assumed to have been committed by the same person, who became known as Jack the Ripper. On August 31st, 1888, the body of Mary Ann Nichols was found, with her throat cut and her abdomen ripped open. From that date to November 9th, 1888, there were four more murders, each similar to the one described above. Each murder victim was a poor women, and each body was mutilated, some even having organs missing. 

As the police investigated the Whitechapel murders, it was assumed that the Ripper was a man who lived in London and worked during the week. This was assumed because the Ripper struck around a certain area of town each time, yet only struck during the weekend. The police first investigated surgeons, butchers, other workers who handled knives, believing that people of these occupations were more likely to kill victims by cutting them with knives. Unfortunately, all the main suspects had alibis that checked out.

There were hundreds of letters sent to the police and the newspapers whose authors claimed to be Jack the Ripper. In the letter known as the "Dear Boss" letter, the author became the first to use the name Jack the Ripper, which became a world famous name. In another letter, known as the "From Hell" letter, the author sent half a kidney, which the author claimed was the kidney of Catherine Eddowes, who had had her kidney stolen during her murder by the Ripper. The author also claimed that he had cooked and eaten the other half of the kidney. Though most letters were immediately thrown out as hoaxes, the "From Hell" letter was kept, though it was never discovered whether the kidney was indeed Eddowes's.

As the murder investigation progressed, the media caught onto the story. Tax reforms had made printing newspapers much cheaper than before, and Jack the Ripper's story was one of the first to be widely distributed throughout the city and the country. 

The End

The true identity of Jack the Ripper was never discovered, though policemen investigated the murders until 1931. Jack the Ripper became a legend, a fairy tale to scare children into being good. The Ripper's appearance also helped to bring media attention to the poor living conditions of London's East End. Jack the Ripper is on our list for being one of the few people who remain famous (or infamous) without actually having a face to put with their name.

The Death of Richard III (August 22nd)

In 1455, the War of the Roses broke out between two families in England: the Lancasters and the Yorks. The two families fought for the throne of England, and during the fight, most nobles in England took a side.

In 1483, Richard, Duke of York, was crowned as Richard the III of England after he usurped the throne from his twelve-year-old nephew, Edward V. The War of the Roses, however, was not over with the crowning of a York.

Richard was contested for the throne by Henry Tudor, the last remaining male member of the House of Lancaster. Because of this, Henry Tudor had the Lancaster family's strongest claim on the throne of England. Henry Tudor had gathered his forces in Frances, and then sailed his army to Milford Haven, Wales.

On August 21, 1485, twelve miles west of Leicester, on Bosworth Field, Henry Tudor's forces met Richard's in battle. Richard could have, for his army was of greater numbers, but at the last minute, several of his most important and powerful barons defected, giving Henry a decisive victory. Though he knew of his impending defeat, Richard is reported to have said, "I will not budge a foot. I will die king of England." Soon afterwards, Richard was unhorsed and killed, leaving Henry Tudor as Henry VII of England. Richard was only thirty-two years old and had been king for only two years when he died.
