Todd will never be forgotten. As neighbors he would swing by on his way home from work to check in on how the family was doing. As a colleagues, we published together and shared ideas about the world. One of the things I liked most about Todd was his predictability. Never did you have to wonder where he stood on issues. He was always collegial and sought ways to include the people he cared most about. He always had a fairly mild disposition and high academic standards. Predictably, any time I hear Journey playing on the radio I am reminded of my friend and college, Todd Christopher Headrick. I often joked with him because neither of us had family in the area my kids could call him “Uncle Todd.” It put a smile on his face. He looked after me in more ways than one, I felt a sense of brotherhood with him, and we would lean on each other in challenging times. Godspeed, my friend.
