Hermann Ebbinghaus (German psychologist)

Hermann Ebbinghaus was a German psychologist known for his pioneering research on memory. In the late 19th century, he conducted experiments to understand how we learn and forget information. Ebbinghaus is famous for developing the "forgetting curve," which illustrates how quickly we lose memories over time without reinforcement. He also introduced the concept of the "spacing effect," highlighting that information is better retained when studied over spaced intervals rather than crammed in one session. His work laid the foundation for modern cognitive psychology and our understanding of learning processes.
