Later a world-renowned scientist, Ivan Pavlov
was born in 1849 in Ryazan to a family of priests. His father had been a priest in the Lazarev Church (demolished in the middle of the 20th century), and all the ancestors of both his parents were priests too. Ironically, Ivan Pavlov chose an academic career, but before that he graduated from the Ryazan church school and then the local theological seminary. During his last year at the seminary, he read Ivan Sechenov's Reflexes of the Brain
, a book that transformed his entire life. Having developed a passion for science, Ivan Pavlov left Ryazan in 1870 to enrol in the St Petersburg university, where his career as a researcher and physiologist began.
