This site presents the human face of chemistry: the people who were behind the major advances the chemical sciences.

• Alice Hamilton was called "a plain nuisance", but her work in pathology and public health saved thousands.
• Boyle's law becomes less cold and abstract when it is connected with a face, even if the face is topped with a wig!
• Marie Curie was a mother, not just a genius scientist, as seen in a photograph of her with her daughters.
• John Dalton's journey that led to atomism started with his avid interest in the weather.

Learn about extraordinary ideas, discoveries, and people not by memorizing formulas but rather by meeting chemists in formal settings, in relaxed moments with their families, and engaged in their work.
