- Lavoisier
- Newton
- Proust

The correct answer is: Proust
- In 1794, French chemist Joseph Proust formulated the law of constant ratios from his work on sulfides, metal oxides, and sulfates.
- This law received much opposition from the scientific community in the 18th century. Dalton's introduction to atomic theory supports this law, and the relationship between these two concepts of his was established in 1811 by the Swedish chemist Jacob his Berselius.
