On September 14, in the year 1849, Ivan Petrovich Pavlov was born in a small village in Ryazan, Russia. Pavlov was originally going to follow in his father's footsteps, to enter priesthood, and even enrolled in a theological seminary, but after reading some works of Charles Darwin, Ivan left the seminary for the University of St. Petersburg in 1870. Pavlov completed a third course of study at the Academy of Medical surgery, and was awarded his first gold medallion. He began to pursue studies in Physiology and chemistry.

He eventually began doing is own research that became very well known, and later was appointed professor of physiology at the Imperial Medical Academy.

In the Year 1903, Ivan published hid findings calling this a "conditioned reflex"� different from innate reflex. He mentioned in it that if the bell were rang...
