Emil Kraepelin is widely regarded as a pioneer in the field of psychiatry, having developed the first ever classification system for mental disorders. An early proponent of a scientific approach to diagnosing mental illness, Kraepelin’s system is still in use today. This article takes a look at the life of Emil Kraepelin, his work and its influence on modern psychiatry.

Early Life 

Emil Kraepelin was born in Neustrelitz, Germany in 1856. He was the eldest child of a highly respected doctor, who devoted his life to improving medical diagnosis and treatment. As a young man, Kraepelin was a diligent student and was encouraged by his father to pursue a career in medicine. He received a medical degree from the University of W├╝rzburg in 1878 and then spent several years working in psychiatric hospitals.

A Scientific Approach to Psychiatry 

During his time working in psychiatric hospitals, Kraepelin observed that many of the patients he treated had similar symptoms. He recognized that there were certain patterns of behavior that could be observed and used to diagnose mental illness. This led him to develop a classification system which organized the various types of mental illness into groups.

Kraepelin’s System 

Kraepelin’s system was the first of its kind, and made a major contribution to the study of mental illness. It divided the various types of mental illness into seven categories based on their symptomology. These included:

Psychotic Disorders:

  1. Schizophrenia
  2. Dementia Praecox
  3. Catatonia
  4. Paranoia

Neurotic Disorders:

  1. Anxiety Disorders
  2. Phobias
  3. Neurotic Depression
  4. Psychosomatic Disorders

It also distinguished between functional (psychiatric) disorders and physical (somatic) disorders, furthering the separation of mental and physical health. This classification system had a significant impact on the way mental illness was viewed, and served as the foundation for all future psychiatric classification systems.


Kraepelin’s classification system was revolutionary and is still in use today. His work significantly advanced the field of psychiatry, providing a basis for modern diagnosis and treatment of mental illness. Following his death in 1926, Kraepelin was widely celebrated as a pioneer in the field and his legacy continues to have an influence today.
