Examples are: Lavoisier, Berzelius, Lomonosov, Kekule, Butlerov, Gmelin, Canizzaro, Heyrowsky, etc.
To list all chemists and their contributions would be a task that would fill volumes and is far beyond the scope of what WikiAnswers is here for. In addition as you do not state your nationality we do not know who would be a foreign chemist to you.
Lavoisier, Mendeleev, Scheele, Berzelius, Ostwald, Proust
It would be challenging to list 20 foreign chemists and their discoveries in a concise manner. However, some significant foreign chemists and their contributions could include Dmitri Mendeleev (creator of the periodic table), Marie Curie (discovered polonium and radium), Linus Pauling (worked on the nature of the chemical bond), and Christian B. Anfinsen (studied protein folding).
Please define "foreign from where" in your "to be edited" question.

Some notable foreign chemists in the field include Marie Curie (Poland/France) who discovered polonium and radium, Dmitri Mendeleev (Russia) who formulated the periodic table, and Linus Pauling (USA) who worked on the nature of chemical bonds.
St. Albert the Great is considered the patron saint of chemists, as he was a medieval philosopher and scientist who made significant contributions to the field of alchemy and chemistry.

examples of foreign biologists and their contributions
Assuming that you mean foreign to the USA, here are some examples.Antoine Lavoisier, who was French, is called the father of chemistry. He was crucial to our understanding of compound formation.Robert Bunsen invented the famous burner as an aid to his work on emission spectra with Fraunhofer. They were German.Dmitri Mendeleev, a Russian, formulated the Periodic Table.John Dalton was crucial in the formation of the atomic theory. He was British, from Manchester.
