“My father … lost his long and arduous battle with cancer this morning,” Wolfgang Van Halen wrote. “My heart is broken and I don’t think I’ll ever fully recover from this loss”

Eddie Van Halen, the legendary guitar innovator and virtuoso who led Van Halen through five decades and three lead singers, establishing himself as one of the all-time great players in rock history, died Tuesday after a long battle with cancer. He was 65.

“I can’t believe I’m having to write this, but my father, Edward Lodewijk Van Halen, lost his long and arduous battle with cancer this morning,” his son Wolfgang Van Halen wrote. “He was the best father I could ever ask for. Every moment I’ve shared with him on and off stage was a gift. My heart is broken and I don’t think I’ll ever fully recover from this loss.”

“40 years ago my life changed forever when I met you,” Van Halen’s ex-wife Valerie Bertinelli wrote. “You gave me the one true light in my life, our son, Wolfgang. Through all your challenging treatments for lung cancer, you kept your gorgeous spirit and that impish grin. I’m so grateful Wolfie and I were able to hold you in your last moments. I will see you in our next life my love.”
