Dmitri Ivanovich Mendeleev

Dmitri Ivanovich Mendeleev was born in Tobolsk, Siberia, on February 7, 1834. Dmitri died January 20,1907 at age 73. He was a blonde haired, blue-eyed boy, and the youngest of 14 children. His become mare Korniliev s family settled in Tobolsk in the early 1700 s and introduced paper and glass devising to Siberia. Ivan Dmitri s father died when he was a young boy, leaving his wife to support the large family. So female horse had to find work to put the children to school.Maria s family owned a glass factory, allowing her t recall over managing the company for a modest wage from which she could support the family. Dmitri being the youngest must have been his mother s favorite child and was provided as many opportunities as she could afford. Form Dmitri s early years, she began to bear mvirtuosoy for Dmitri to attend the university. He spent many hours in the glass factory his mother operated, acquisition from the chemist about the concepts behind glass making and from the glass blower about the art of making glass.At age 14, he was attending the Gymnasium in Tobolsk. In that year a southward major family tragedy occurred, the glass factory burned down. There was no money to rebuild and the completely money was the money saved for Dmitri to go to the university. Maria was non about to give up her dreams for her son. She knew that Dmitri had to go to school on a scholarship. So she paused Dmitri to improve his grades and prepare for entrance exams. Dmitri did not insufficiency to or cared about other subjects other consequently science. He entangle that history and Latin were dead subjects and expend of his time.In 1849, the family moved to Moscow. Because of political problems university was reluctant to admit anyone from outside of Moscow. Dmitri s mother did not want to give up here, so the family moved again to St. Petersburg. Dmitri took the entrance exams at Pedagogical Institute. He did not get the best grades but well enough to be admitted to the science checker-training program on a full scholarship. Maria died shortly after Dmitri s acceptance at St. Petersburg. Shortly after his child died, both from tuberculosis. Dmitri was now alone.He got tuberculosis also and the doctor told him he had two years to stand firm unless he moves somewhere more suitable. Even with this disease he graduated on time. He had his proximo planed and did not want to die yet, so he move to Simferopol in the Crimean Peninsula. Between 1859 and 1861 he canvass the densities of gases with Regnault, A. P. Borodin and Cannizzaro. These people had great influences in his life. He began to teach back at St. Petersburg in 1863. In 1866 he became known as Professor of Chemistry at the University and was made Doctor of Science.He love to teach and spent most of his time in his classroom. Lot of his lab work including the periodic table was make on his spare time. In 1863 Dmitri married Feozva Nikitchna Lascheva. They had two children. A boy named Volodya, and a daughter named Olga. Mendeleev never really loved Feoza and spent little time with her. In January 1882 he divorced Feozva so he could marry his niece s best friend Anna Ivanova Popova. She was a lot younger than Dmitri but the town loved each other. They had four children together. He made several publications.Most famous one was Organic Chemistry, which was create in 1861 when he was 27 years old. This book won the Domidov Prize. The first edition of Principles of Chemistry was printed in 1868. Both of these books were classroom texts. His greatest accomplishment was the stating of the Periodic Law and the development of the Periodic table. He felt that there was some type of order to the elements, and spent more than thirteen years of his life assemblage data and assembling the concept, initially with the idea of resolving some of the chaos in the field for his students.Dmitri was one of the first modern-day scientists that did not rely on his own work but in s cientists about the world in order to receive data that they have collected. Then he used their data along with his own data to arrange the elements according to their properties. By 1869 he assembled detailed descriptions of more then 60 elements. On November 29, 1870 Dmitri took his concept even further by stating that it was possible to predict the properties of undiscovered elements.He then proceeded to make predictions for three new elements and suggested several properties of each, including density, radii, and combining ratios with oxygen, among others. People did not believe his theories. They honorable ignored it and did not take Dmitri s work seriously. In 1875 when Frenchman Lecoq de Boisbaudran discovered one of the predicted elements with he named Gallium, Dmitri ideas were taken seriously. The other two elements were discovered later and their properties were found to be remarkably similar to those predicted by Mendeleev. He was 35 years old when the initial paper w as presented.Throughout the remainder of his life, Dmitri Mendeleev received numerous awards from carious organizations including the Davy Medal from the Royal Society of England in 1882, the Copley Medal, the Society s highest award in 1905. He got unearned degrees from universities around the world. Dmitri Mendeleev s work means a lot to us. Imagine how hard it would have been to memories the elements without a periodic table? I admire Dmitri, because not only for his achievements but the way he achieved them. He had a tough childhood and yet he turned out a brilliant man. Dmitri did not give up his dreams but kept chasing after them.
