Biographical studies are undertaken for many reasons, depending not only on the people being studied, but also on those doing the studying. Let me address the second set of reasons. The sine qua non for me is two-fold: (1) there must exist relatively unknown facets of the subject's life, work, or extensions of that work by others, and (2) a wealth of source material must be available for mining, somewhere. The detective work of locating, excavating, and refining the material is rewarding as a kind of problem-solving. millay

But there is a deeper reason for researching the lives of others who have gone before. It is a kind of defiance reflected by Edna St. Vincent Millay's poem printed on this page. These words were spoken by a leading twentieth-century mathematician, Hermann Weyl, in his memorial address soon after the death of the mathematician Emmy Noether. The poem speaks for many biographical researchers and writers.

Each biographical study here consists of a brief summary of the person's life and work, including, as may be appropriate and available, a photographic or other image, list of publications, and links. In the case of the New Harmony naturalists, there are quite a number of onsite links to species named by them or named in their honor. Many professional photographers have kindly given permission for the use of their work in these links.

For subjects about whom a book-length biography exists you'll find here only brief summaries with references to the literature. For lesser-known individuals, you'll find more extensive accounts.

The biographical sketches are grouped as follows:

New Harmony Scientists, Educators, Writers & Artists (New Harmony is a historic town in Indiana);
Emmy Noether, Mentors and Colleagues;
