Ivan Pavlov : biography

September 14, 1849 - February 27, 1936

Ivan Petrovich Pavlov ( 14 September (26 September) 184927 February 1936) was a famous Russian physiologist. From his childhood days Pavlov demonstrated intellectual brilliance along with an unusual energy which he named "the instinct for research". Inspired by the progressive ideas which D. I. Pisarev, the most eminent of the Russian literary critics of the 1860s and I. M. Sechenov, the father of Russian physiology, were spreading, Pavlov abandoned his religious career and decided to devote his life to science. In 1870 he enrolled in the physics and mathematics faculty at the University of Saint Petersburg to take the course in natural science. Ivan Pavlov devoted his life to the study of physiology and sciences, making several remarkable discoveries and ideas that were passed on from generation to generation. He won the Nobel Prize for Physiology or Medicine in 1904.

Early life and schooling

Ivan Pavlov, the eldest of eleven children, was born in Ryazan (now the Central Federal District) of Russia. His father, Peter Dmitrievich Pavlov (1823–1899), was a village priest. His mother, Varvara Ivanovna Uspenskaya (1826–1890), was a devoted 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.Asratyan, p. 8 Although able to read by the age of 7, Pavlov was seriously injured when he fell from a high wall onto stone pavement;Asratyan, p. 9 he did not undergo formal schooling until he was 11 years old as a result of his injuries.

Pavlov attended and graduated from the Ryazan Church School before entering the local theological seminary. However, in 1870, Pavlov left the seminary without graduating to attend the university at St. Petersburg where he enrolled in the physics and math department and took natural science courses. In his fourth year, his first research project on the physiology of the nerves of the pancreasAsratyan, pp. 9–11 won him a prestigious university award. In 1875, Pavlov completed his course with an outstanding record and received the degree of Candidate of Natural Sciences. However, impelled by his overwhelming interest in physiology, he decided to continue his studies and proceeded to the Academy of Medical Surgery. While at the Academy of Medical Surgery, Pavlov became an assistant to his former teacher, Tyson, but left the department when Tyson was replaced by another instructor.

After some time, Pavlov obtained a position as a laboratory assistant to Professor Ustimovich at the physiological department of the Veterinary Institute.Asratyan, p. 12 For two years, Pavlov investigated the circulatory system for his medical dissertation. In 1878, Professor S.P. Botkin, a famous Russian clinician, invited the gifted young physiologist to work in the physiological laboratory as the clinic's chief. In 1879, Pavlov graduated from the Medical Military Academy with a gold metal award for his research work. After a competitive examination, Pavlov won a fellowship at the Academy for postgraduate work.Asratyan, p. 13 The fellowship and his position as Director of the Physiological Laboratory at the clinic of the famous Russian clinician, S. P. Botkin enabled Pavlov to continue his research work. In 1883, he presented his doctor's thesis on the subject of The centrifugal nerves of the heart and posited the idea of nervism and the basic principles on the trophic function of the nervous system. Additionally, his collaboration with the Botkin clinic produced evidence of a basic pattern in the regulation of reflexs in the activity of circulatory organs.

Married life and family problems

Ivan Pavlov married Seraphima Vasilievna Karchevskaya on 1 May 1881. They met in 1878 or 1879 when Seraphima went to St. Petersburg to study at the Pedagogical Institute. Seraphima, called Sara for short, was born in 1855. In her later years, she suffered from ill health and died in 1947. The first nine years of their marriage were marred by financial problems. Pavlov and his wife often had to stay with others in order to have a home. For a while they even had to live apart so they could find hospitality. Although their general lack of money caused despair, material welfare was a secondary consideration.
