List of people considered father or mother of a scientific field

The following is a list of people who are considered a "father" or "mother" (or "founding father" or "founding mother") of a scientific field. Such people are generally regarded to have made the first significant contributions to and/or delineation of that field; they may also be seen as "a" rather than "the" father or mother of the field. Debate over who merits the title can be perennial.
