Stephen’s passions reached far beyond his career. He was tirelessly curious about the world, drawn to travel, environmental stewardship, genealogy, history, art, architecture, mathematics, and literature. Whether leading a conversation about history or admiring a piece of art, he approached every subject with both intellect and heart. His mind was sharp, but it was his compassion and generosity of spirit that truly defined him.
