The periodic table. It is a chart of all the known elements. Almost everyone has at least an idea of what it is, but do they know who created it? Dmitri Mendeleev was not the first to know of the elements, but he was the first man to sort them. Mendeleev was born in Russia on the 8th of February, 1834. A large family surrounded him, and his father owned a glass factory, which he closed. It was later re-opened by Mendeleev’s mother when her husband went blind. Mendeleev’s father died when young Dmitri was thirteen and was shortly followed by his factory, which burned down two years later. The following year, Mendeleev moved to Saint Petersburg, which was, at the time, the capital city of Russia. There,

It was held in Karlsruhe, Germany and attended by many chemists, including Mendeleev. At the conference, the scientists discussed atomic weights and how to determine them. They also talked about Avogadro's Law, which stated, “All gases, at the same volume, temperature, and pressure, contain the same number of

He wrote a 500-page book called Organic Chemistry in only 61 days, and it won the Demidov Prize. Mendeleev bounced from job to job until he finally settled into a job at the University of Saint Petersburg as the Chair of General Chemistry. While working there, he couldn’t find a chemistry textbook that he wanted for the students, so he decided to write his own. Mendeleev did not want a book with just facts, but he wanted to inspire the students to become scientists. In 1869, he had written and published The Principles of Chemistry. According to Mendeleev, he wanted “to incite in the reader a spirit of inquiry which, unsatisfied with speculative reasoning alone, should subject every idea to experiment, should excite the habit of stubborn work, and should necessitate a knowledge of the past and a search for the fresh threads to complete the bridge over the bottomless unknown.” The texbook became very popular in many countries. Mendeleev wanted to find a way to sort all the elements according to a certain pattern, but he had no idea what that pattern was. He wrote the elements on cards, along with their atomic weights. Mendeleev tried to figure it out for hours, then fell asleep. When he woke up, he knew the pattern. Mendeleev had figured it out in a dream! He wrote, “In a dream I saw a table where all the elements fell into place as required. Awakening, I immediately wrote it down on a piece
