## Summary
Joseph-Nicolas Delisle was a French astronomer best known for inventing the Delisle scale, a temperature measurement system. His work in astronomy and meteorology contributed to scientific understanding during his time.

## Biography
- Born: April 4, 1688 (approximate date)
- Nationality: French
- Education: Not specified in source material
- Known for: Inventing the Delisle temperature scale
- Employer(s): Royal Academy of Sciences, Paris Observatory
- Field(s): Astronomy, meteorology

## Contributions
- **Delisle Scale (1732)**: Invented a temperature scale where 0° represented the boiling point of water and 100° represented freezing, which was later refined and replaced by the Celsius scale.
- **Astronomical Observations**: Contributed to astronomical research, though specific works are not detailed in the source material.
- **Meteorological Studies**: Made significant contributions to meteorology, including temperature measurement techniques.
