1) Raoul Bott wrote a relatively long Autobiographical Sketch and a more detailed article entitled The Dozinger Years (1932-1939) in Vol. 1 of his collected papers, cited below. Much anecdotal history can also be found in his later expository papers.

6) The following two preprints, coauthored by confirmed speakers, are two wonderful examples of how Raoul Bott’s early work has a profound influence on current research:

Peter Teichner’s (coauthored) preprint, K-Theory: From Closed Geodesics to SUSY Field Theories is available at: http://math.berkeley.edu/~teichner/Papers/Bott-EFT.pdf

Nancy Hingston’s (coauthored) preprint, Loop Products and Closed Geodesics is available at: http://www.math.ias.edu/~goresky/pdf/loops.pdf
