The History of the Periodic Table of Elements Dmitri Mendeleev and the early Periodic Table Dmitri Mendeleev was born in Tobolsk, Siberia; on February 7, 1834 .He was the youngest of 14 children born to Maria Dmitrievna Korniliev and Ivan Pavlovitch Mendeleev. His father was director of the local gymnasium. Maria Korniliev's family settled in Tobolsk in the early 1700's and introduced paper- and glass-making to Siberia. Unfortunately, Ivan died when Dmitri was quite young, leaving his wife to support the large family. The death hit them hard economically especially for a large family, which meant that Maria had no other choice but to find work. Maria's family owned a glass factory and they allowed her to take over managing the company so she could support the family. Dmitri, being the youngest, appears to have been his mother's favorite child and was provided as many opportunities as she could afford. From his early years, she began to save money for Dmitri to attend the university.
As he grew older, it became apparent that he had a bright future. At the age of 14, he was attending the Gymnasium in Tobolsk and his mother was continuing to plan for his future. In that year, however, a second major family tragedy occurred; the glass factory burned to the ground. The family was devastated. Maria was not about to give up her dreams for her son. She knew at this point that Dmitri's only hope to go on to school was to win a scholarship. So in his final years at the gymnasium, Maria pushed Dmitri to improve his grades and prepare for entrance exams. After much nagging from his mother and Bessargin, Mendeleev passed his gymnasium exams and prepared to enter the university. In 1849 they moved Moscow. At this point the family included Maria, Dmitri, and Elizabeth (Dmitri's older sister). In Moscow, they entered a climate of considerable political uproar, which made the university reluctant to admit anyone from outside of Moscow. Mendeleev was rejected. Maria did not give up, however, and the family headed for St. Petersburg. Mendeleev was left alone to face his work at the university. Dmitri fell right into his work at St. Petersburg. Mendeleev graduated and was awarded the medal of excellence for being first in his class. Mendeleev already had his life's ambitions in mind and, hoping to extend his life as long as possible, he moved to Simferopol in the Crimean Peni...

  • Mendeleev's First Periodic Table

    498 Words  | 1 Pages

    Although some of the elements have been known for thousands of years, our understanding of many elements is still young. Mendeleev’s first Periodic Table contained only 63 elements, and about that many were discovered in the following 100 years. Just like countries, emperors, philosophers, and cities, elements have histories, too.“The Disappearing spoon” by Sam Kean, is a detailed history of the elements on the Periodic Table. Kean does a important job of telling every single element’s journey throughout the history of mankind: from the earliest times, when chemistry was intermingled with alchemy, to these days of modern chemistry. For example: Thallium is considered the deadliest element, pretending to be potassium to gain entry into our cells where it then breaks amino acid bonds within proteins. The CIA once developed a plan to poison Fidel Castro by dosing his socks with thallium-tainted

It is fair to say that although his parents' direct musical contribution during his upbringing and musical development was minimum, their place in the Russian society, his father's career and his connections highly influenced young Stravinsky. Nevertheless, his parents would never allow his to pursue a career in music and thus he entered St Petersburg university to study law. During the course of his studies, he spent most of his time playing the piano, taking part in performance and pursuing his passion for music, therefore, he failed law school due to low attendance.
