Weber Shandwick VP Christopher Neumann died Jan. 6 after a single-engine plan crash while en route to the Detroit suburb of Troy, Mich.
Todd Lloyd, the 51-year-old president of rental services company Chair Covers & Linens and a licensed pilot who was Neumann's partner, was also killed in the crash, which occurred after takeoff from Boyne City Municipal Airport.
Neumann, 38, joined WS in 2011 and worked on the General Motors account on video and marketing projects.
Weber Shandwick called Neumann a "deeply valued colleague, gifted professional and friend."
Federal authorities are investigating the crash to determine its cause.
Neumann was a resident of Birmingham, Mich.
