Sept. 6th 1828-Aug, 17th 1886
Aleksandr Butlerov (born Sept. 6, 1828, Chistopol, Russia—died Aug. 17, 1886, Butlerovka), a Russian Chemist who helped advanced the ideas on chemical structure by creating his own concept on the structure of chemistry. This theory stated that "the chemical nature of a molecule is determined not only by the number and type of atoms but also by their arrangement. He foresaw and demonstrated the existence of isomers (molecules composed of the same atoms but in different arrangements), such as the two butanes and three pentane"(citation). In 1866 Aleksandr Mikhaylovich Butlerov made the first sample of isobutane.
