My father, Matt Struth Gemmell. He's never stopped being interested in things, he knows how to persevere (to a degree that my generation and later ones would scarcely comprehend), and he understands the nature of people. I use all these qualities myself every day in my work.

He also gave me my love of written language, and unconditional encouragement no matter what career path I chose for myself. He has his flaws just like any of us, but I deeply respect his opinion, regardless of the topic.
