Principal Sources: Milestones in Chemistry Calendar, Copyright © 1996, remains the principal source of information; however, I have checked (and in some cases corrected) its birth dates. Chemical and Engineering News "Top 75" (75th anniversary issue, 1/12/98) and Biographical Encyclopedia of Scientists edited by John Daintith et al. (Institute of Physics, 2nd ed, 1994) are other important sources. Women in Chemistry and Physics : a Biobibliographic Sourcebook, edited by Louise S. Grinstein, Rose K. Rose, and Miriam H. Rafailovich and Notable Women in the Physical Sciences edited by Benjamin F. and Barbara S. Shearer have helped me to add several women to the calendar. The Illustrated Almanac of Science, Technology, and Invention by Raymond L. Francis is the source of several entries. Thanks to all interested readers who have suggested events for inclusion; Lucio Gelmini has been particularly helpful in this regard.

Dates are given according to the Gregorian calendar to the extent I could find them. (Note: this applies particularly to 19th-century Russians.)
