Fans and colleagues alike are grieving this week over the losses of actor Hayden Panettiere, and ESPN founder William F. Rasmussen. 

Panettiere, 36, was a lifelong performer, especially well-known for her roles in Heroes as Claire Bennet (aka The Cheerleader), and in Nashville as Juliette Barnes. She started working in the industry at just 11 months old, appearing in commercials, and was cast at at age four in One Life to Live. While she was celebrated for her talents, she later wrote about the difficulties that come with being a child actor in her memoir, This is Me: A Reckoning. 

In her book Panettiere wrote she had learned to “walk hand in hand with my triumphs and my tragedies, because they have made me who I am.”

Rasmussen, 93, was often described as a sports-fan-turned-broadcaster whose entrepreneurial skills led him to create the first 24-hour sports network, changing sports television as we know it. 

ESPN chairman Jimmy Pitaro said, “Bill was a remarkable man – a visionary and an innovator who conceived the idea of a network entirely devoted to sports.” USA Today called him “The Father of Sports Television.”
