In a memorable address given at the International Congress of Mathematicians in Paris in 1900, David Hilbert, perhaps the most respected mathematician of his time, developed a blueprint for mathematical research in the new century.

The collections of problems he presented in that address has become a guiding inspiration to many mathematicians, and those who have succeeded in solving or advancing their solutions form an Honors Class among research mathematicians.

With the support of many of the major players in the field, the author has written an engaging account of the achievements of this Honors Class, covering mathematical substance and biographical aspects.
