Don and Mimi Galvin appeared to be living the American dream. After World War II, Don's work with the Air Force brought them to Colorado, where their 12 children perfectly spanned the baby boom—the oldest born in 1945, the youngest in 1965. But behind their idyllic profile there were psychological breakdowns, sudden outbursts of violence and clandestine abuse. By the mid-1970s, six of the 10 Galvin boys were diagnosed as schizophrenic. Robert Kolker’s latest book “Hidden Valley Road: Inside the Mind of an American Family” documents the life of a family that seemed to carry an unfathomable burden. Join us for a discussion of the story that inspired the book in this installment of Leonard Lopate at Large on WBAI.
