He arrived at work at the same time every morning, fed his dogs at the same time each day, held weekly meetings that he called his 'Wednesdays' regularly for 15 years at his laboratory, and it is even said that he would leave Leningrad for his vacation in Estonia on vacation on the same day each year. Pavlov was a sagacious operator who kept a strict schedule of his working hours and habits. His laboratory has been carefully preserved.

The next year, in February 1936, at the age of 86, Ivan Petrovich Pavlov died of pneumonia in Leningrad. When Adolf Hitler came to power in Germany, Pavlov made his peace with the Soviet government, and in 1935, they built a laboratory for him. Pavlov's reprimands of the government, however, did not censure his research. After the murder of Sergei Kirov in 1934, Pavlov wrote several letters to Molotov criticizing the mass persecutions and subsequently demanded the clarification of cases pertaining to several people he knew personally. In 1924, when the sons of priests were expelled from the Military Medical Academy in Leningrad (the former Imperial Medical Academy), he resigned his chair of physiology announcing, 'I also am the son of a priest, and if you expel the others I will go too!' (Crystal 1995). Pavlov then began to publicly denounce communism, stating that the basis for international Marxism was false. But even this praise ceased after Pavlov returned from his first visit to the United States in 1923. Despite this, however, Pavlov continued to praise the government for its support of scientific research. However, Pavlov vehemently opposed such an application. Pavlov and his research thrived within the communist Soviet government, as some government officials perceived his research as having invaluable potential for brainwashing. By 1907, he was elected as the Academician of the Russian Academy of Sciences and was given an honorary doctorate from Cambridge University in 1912. However, a year earlier, in 1903, Pavlov had begun his famous research on the reflex reactions of animals, which he continued thereafter. Then, in 1904, Ivan Pavlov received the Nobel Prize in Physiology or Medicine for his accomplishments on the physiology of digestive glands. He observed that even in the absence of food, the stomach excreted gastric fluids. It was in 1889 that Pavlov surgically altered a dog's digestive system so that it would eat, but the food would not reach its stomach. In 1897, Pavlov published his Lectures on the Functions of the Principal Digestive Glands. From 1891 to 1900, Pavlov did the majority of his research on the physiology of digestion. By 1891, Pavlov became the director of the department of physiology at the Institute of Experimental Medicine. A year later, in 1884, Pavlov was appointed lecturer in physiology at the Military-Medical Academy. In 1883, Pavlov received his received his medical doctorate degree from the Imperial Medical Academy and submitted his doctoral thesis entitled The Centrifugal Nerves of the Heart. Despite these tragedies, two children survived, one son and one daughter, Vladimir and Vera. After Victor's death, Pavlov, who had always followed a strict schedule, began to suffer from insomnia. The death of his children affected Pavlov profoundly. Seraphima suffered from a miscarriage, their son Wirchik died unexpectedly as a young child another son, Vsevolod, died in 1935, and a third son, Victor, died in the White Army. In 1881 Pavlov married Seraphima (Sara) Vasilievna Karchevskaya. By 1875, he graduated from the University of Saint Petersburg, and in 1876 began his studies in medicine at the Military-Medical Academy, from which he graduated in 1879. In 1870 Pavlov enrolled in the Natural Sciences program at the University of Saint Petersburg, where he studied physiology and chemistry under Dimitri Mendeleyev. Pisarev, Pavlov abandoned his religious career to become a man of science. Sechenov, The Origin of Species by Charles Darwin, and being stimulated by the ideas of D.I. After reading the writings of Russian physiologist I.M. In his early years, Pavlov attended the Church school and began his higher education at the Ryazan Theological Seminary, which he graduated from in 1869. Consequently, it was expected that Pavlov would become a seminarian. For the previous six generations, the Pavlov men had served the Russian Eastern Orthodox Church. His father, Peter Dmitrievich Pavlov, was one of Ryazan's most respected clergymen. Ivan Petrovich Pavlov was born in Ryazan, Russia on September 14, 1849.
