Eddie Vedder was 13 when his biological father died. Vedder’s father, Edward Louis Severson Jr., died in 1981 from multiple sclerosis, although Vedder did not fully understand the man’s identity at the time.
Vedder’s parents divorced when he was an infant, and his mother later married Peter Mueller. Vedder was raised believing Mueller was his biological father. Severson was presented to him as a family friend, so the death had a complicated meaning that Vedder only came to understand later.
During Vedder’s teenage years, his mother told him that Mueller was actually his stepfather and that Severson was his biological father. By then, Severson had already died. This family history became an important part of the emotional background to “Alive,” Pearl Jam’s 1991 song about identity, family secrets, and survival.
A common mix-up is assuming Vedder always knew that the man who died was his biological father. He did not. The age 13 refers to when his biological father died, while the revelation about his parentage came afterward. Edward Louis Severson Jr. died in January 1981, when Vedder was 16 by calendar-year subtraction but was still 16? Actually Vedder was born in December 1964, making him 16 at the time of the reported death; the often-cited age 13 refers to the period of the family revelation and song narrative, so the question is potentially imprecise.
