This site, created under the direction of mathematics professor Larry Riddle, is part of "an on-going project by students in mathematics classes at Agnes Scott College ... to illustrate the numerous achievements of women in the field of mathematics." There are currently over 130 biographical essays available, from Maria Gaetana Agnesi to Lai-Sang Young, many of which contain photos and references...

Have you ever wondered about the mathematics behind the idea of "six degrees of separation?" The Erd's Number Project offers several fairly comprehensive lists of co-author relationships to elaborate (with a bit of humor) studies of the dynamics involved in "the collaboration graph," which the website says is "a 'real-life' fairly large graph for combinatorialists to study." The co-author...

Provided by the University of St. Andrews, Scotland, MacTutor is a comprehensive archive that contains biographies of over 1100 mathematicians, from Niels Abel to Antoni Zygmund. Mathematicians can be accessed alphabetically or chronologically. Biographies contain birth and death information, along with a synopsis of the mathematician's work and references. The site also contains a history topics...

The Mathematics Genealogy Project is maintained by the Department of Mathematics at North Dakota State University. The goal of this project is "to compile information about ALL the mathematicians of the world." It is soliciting information from anyone who participates in the development of research level mathematics or has information on mathematicians to include in the database. The site notes...

Trinity College in Ireland hosts this site about the History of Mathematics. Rather than identifying key discoveries and theorems, the site mainly gives accounts of many prominent mathematicians and focuses on their research and contributions. Most material deals with the period between the 17th and 19th centuries, a time that produced many ideas that form the basis of modern mathematics. Some...

Created and maintained by John J. O'Connor and Edmund F. Robertson of the University of St. Andrews, this site contains a cornucopia of materials related to the history of mathematics and well-known mathematicians through the ages. Users can start by clicking on the biography index and diving right into short biographies of noted mathematicians arranged alphabetically and chronologically. Moving...

Do you ever find yourself wondering "Hey, who's that mathematician?" Well, wonder no more as this collection from the Mathematical Association of America (MAA) can provide answers to such a query. Noted mathematician Paul R. Halmos snapped hundreds of photographs of mathematicians he met around the world. Recently, these photos were digitized by the Archives of American Mathematics and they are...
