February 8th 1836- February 2nd, 1907
When he was 13, His father passed away and then his mother's family's glass factory burned down after that. So in 1849 his mother took him across the whole state of Russia, looking for a higher education for him even though they were very poor. The University of Moscow rejected him, however he was soon able to get into the Main Pedagogical Institute in St.Petersburg. During his later life as a chemist he created the periodic table (although not accepted until 20 years after he discovered it). However that was by far his largest and possibly largest contribution by anyone to chemistry and the atomic theory.
