Ebbinghaus was born in a merchant family in Bamen, Germany. He entered Bonn University to study history and linguistics at the age of 17. 1873 received his doctorate from Bonn University. 1875- 1878 studying in Britain and France. Influenced by Fechner, he began to study memory by experimental methods. 1886 Associate Professor, Berlin University. 1890, Ebbinghaus co-founded the Journal of Psychology and Sensory Physiology. 1894 Professor, Braus Lei University. 65438 to 0905 Professor of Harley University.
He published a book on memory in 1885. There is an experiment mentioned in it, and he himself is the subject of the experiment. He tried to recite a series of meaningless syllables (two consonants and a vowel) in groups of three letters. He observed how long it took him to recite the list to measure his learning speed. After a while, he checked how many times he needed to read through it before reciting the list again. He found some forgetting rules. The knowledge learned first is quickly forgotten, and then it will slow down. It's hard to forget what you've remembered for a long time. This is the famous "forgetting curve", also called "Ebbinghaus curve".
