Faces of mathematics

In sketching the history of work on the Millenium Prize Problems, the editors made the interesting choice to include more than a hundred photos of the mathematicians involved. Great pictures and commendable variety: different pictures for those who are mentioned multiple times because of their work on more than one problem, such as John Tate (Birch--Swinnerton-Dyer Conjecture and Hodge Conjecture) and André Weil (Hodge Conjecture and Riemann Hypothesis). But they had to repeat the portrait of Euler a few times. . .
