The biographies on this web site should be no more than 2 pages in length, along with a 3- or 4-line summary for the main page. See draft page for examples.
If you know of a more extensive web site that features your mathematician, you may want to include a link to that site. Alternatively, if you know of a web page for someone appropriate that we should point to, please let us know that too.
Please contact David Kullman (firstname.lastname@example.org) or Thomas Hern (email@example.com) about the site or the guidelines.
