The Mathematical Association of America's William Lowell Putnam Competition

The William Lowell Putnam Mathematical Competition is an annual contest for college students established in 1938 in memory of its namesake.

Each year on the first Saturday in December, over 2000 students spend 6 hours (in two sittings) trying to solve 12 problems. Individual and team winners (and their schools, in the latter case) get some money and a few minutes of fame.

Cash prizes for the top five teams in recent years ranged from $25,000 to $5,000. Recent cash prizes for the top five individuals have been $2,500 each. Below the individual winners for each year are listed in alphabetical order.

The Elizabeth Lowell Putnam Prize was established in 1992 to be "awarded periodically to a woman whose performance on the Competition has been deemed particularly meritorious". Recent winners of the Elizabeth Lowell Putnam Prize have received $1,000. Over the years many of the winners of the Putnam competition have become distinguished mathematicians. A number of them have received the Fields Medal and several have won the Nobel Prize in Physics.
