ACKNOWLEDGMENTS

We would like to thank Ron Rapoport, Jasper Rosenberg, Elliot Marks, and Jenise Aminoff for their extremely thorough comments.

Of course we thank our editor, Jonathan Simcosky, for his guidance; Joy Acquilo, who believed in the book; and Liz Heinecke, who was kind enough to let us add to the wonderful series of books she created.

From day one, we wanted Kelly Anne Dalton to be our illustrator. We are blown away by her talent and ability to subtly include details from the biographies into her work.

Thank you so much to Heather Godin, art director extraordinaire, who was irreplaceable in helping us achieve our vision, and to Glenn Scott, a true pro in capturing even the smallest of details with his camera. M. Godin provided the super cute artwork for the turtle and dog tessellations, and J. Yoder created the awesome elephant tessellations. We also thank Zack Chung for sharing his thoughts on dyslexic-friendly fonts.

We also thank Fan Chung for providing fun stories about Yau and other insight into many of today’s mathematicians.

And of course, we thank all the kids whose smiling faces light up this book and their parents for bringing them to us, especially with the added challenges of the COVID-19 pandemic.
