Allendoerfer Award

The Carl B. Allendoerfer Awards, established in 1976, are given for articles of expository excellence published in Mathematics Magazine. The Awards are named for Carl B. Allendoerfer, a distinguished mathematician at the University of Washington and President of the Mathematical Association of America, 1959-60. This is an award of $500. Up to two of these awards are given annually at the Summer Meeting of the Association.

Most of these award-winning articles are available in pdf form in MathDL. Click here to find links to the articles
