About Ivan Pavlov
Ivan Petrovich Pavlov (Russian: Иван Петрович Павлов, IPA: [ɪˈvan pʲɪˈtrovʲɪtɕ ˈpavləf]; 26 September [O.S. 14 September] 1849 – 27 February 1936) was a Russian and Soviet experimental neurologist and physiologist known for his discovery of classical conditioning through his experiments with dogs. Pavlov also conducted significant research on the physiology of digestion, for which he was awarded the Nobel Prize in Physiology or Medicine in 1904. == Education and early life == Pavlov was born on 26 September 1849, the first of ten children, in Ryazan, Russia. His father, Peter Dmitrievich Pavlov (1823–1899), was a village Russian Orthodox priest. His mother, Varvara Ivanovna Uspenskaya (1826–1890), was a homemaker. As a child, Pavlov willingly participated in house duties such as doing the dishes and taking care of his siblings. He loved to garden, ride his bicycle, row, swim, and play gorodki; he devoted his summer vacations to these activities. Although able to read by the age of seven, Pavlov did not begin formal schooling until he was 11 years old, due to serious injuries he had sustained when falling from a high wall onto a stone pavement. From his childhood days, Pavlov demonstrated intellectual curiosity along with what he referred to as "the instinct for research". He attended the Ryazan church school before entering the local theological seminary.
