In 1986 an anonymous donor gave the Mathematical Association of America funds sufficient to support a prize honoring inspiring and dedicated teachers. The prize is to be named after Merten M. Hasse, who was a former teacher of the donor, and who exemplified these qualities of a fine teacher. The prize is designed to be an encouragement to younger mathematicians to take up the challenge of exposition and communication.

The Merten M. Hasse Prize is for a noteworthy expository paper appearing in an Association publication, at least one of whose authors is a younger mathematician, generally under the age of forty. The prize is to be $1,000, together with a certificate, and is to be awarded at Summer Meetings of the Mathematical Association of America in odd-numbered years. The award is to be made for material published during the four calendar years beginning January 1 five years prior to the time of the award. The prize may be given for a paper which has already been recognized by an Allendoerfer, Ford, or Pólya Award.

MAA members may recommend books to be considered for the Merten Hasse Prize by completing the brief survey here.
