Erick Lee Purkhiser (October 21, 1946 – February 4, 2009), better known as Lux Interior, was an American singer and a founding member of the punk band The Cramps from 1972 until his death in 2009 at age 62.
Born in Akron, Ohio, he grew up in its nearby suburb of Stow and graduated from Stow High School.
He met his wife Kristy Wallace, better known as Poison Ivy, a.k.a. Ivy Rorschach, in Sacramento in 1972, when he and a friend picked her up when she was hitchhiking. The couple founded the band after they moved from California to Ohio in 1973, and then to New York in 1975, where they soon became part of the flourishing punk scene.
Lux Interior died at 4:30 a.m. on February 4, 2009, at Glendale Memorial Hospital in California. The cause of death was aortic dissection. He is survived by his wife Ivy and two brothers, Michael Purkhiser and Ronald "Skip" Purkhiser. The memorial service for Lux was held on February 21 at the Windmill Chapel of the Self-Realization Fellowship Lake Shrine. Lux's brother Michael also provided insight into his relationship with Lux in a newspaper article.
