## Summary
Ernst Heinrich Weber was a German psychologist (1795–1878) known for his contributions to psychophysics, particularly the formulation of the Weber–Fechner law, which established a relationship between stimulus intensity and perceived sensation. He was a professor at Leipzig University and a member of multiple scientific academies, including the Royal Prussian Academy of Sciences and the Saxon Academy of Sciences and Humanities.

## Biography
- Born: June 24, 1795, in Leipzig, Saxony
- Nationality: German
- Education: Studied at Leipzig University and the University of Berlin
- Known for: Formulating the Weber–Fechner law in psychophysics
- Employer(s): Leipzig University, Royal Prussian Academy of Sciences, Saxon Academy of Sciences and Humanities
- Field(s): Psychology, psychophysics

## Contributions
- **Weber–Fechner Law (1860)**: Developed the principle that the minimum perceptible increase of stimulus is proportional to the stimulus, and that sensation increases logarithmically with stimulus intensity. This law became foundational in psychophysics.
- **Research on Sensory Perception**: Conducted experiments on human sensory perception, particularly in vision and hearing, contributing to the understanding of how humans perceive and respond to stimuli.
- **Academic Leadership**: Served as a professor of physiology and psychology at Leipzig University, shaping the educational landscape in these fields.
- **Scientific Memberships**: Affiliated with prestigious academies, including the Royal Prussian Academy of Sciences and the Saxon Academy of Sciences and Humanities, enhancing his influence in the scientific community.
