Ace Frehley, the founding guitarist of the rock band KISS, died at age 74 due to complications from a brain hemorrhage (brain bleed) caused by a fall he suffered in his studio in late September 2025. Following the fall, he was hospitalized and placed on life support but did not recover. His family confirmed that he passed away peacefully surrounded by loved ones in Morristown, New Jersey. The fall resulted in a serious intracranial hemorrhage, a life-threatening condition where blood pools between the brain and skull, leading to his rapid health decline and cancellation of his remaining 2025 tour dates. Frehley's death is the first among the original KISS members, marking a significant loss in rock music history.
In summary, Ace Frehley died from a brain hemorrhage caused by a fall, which ultimately led to his being placed on life support and his subsequent passing.
