About the author
Louis Daniel Frenzel Jr. was an American wildlife biologist and professor. Sources about his life describe him as a professor of wildlife biology at the University of Minnesota from 1969 to 1984, and also note earlier work with the biology department at Macalester College.
As an author, he is best known for work connected to Ecological Studies of the Timber Wolf in Northeastern Minnesota, a 1971 U.S. Forest Service research publication. In that volume, Frenzel contributed to research on wolf behavior, deer predation, and related ecological questions in northern Minnesota.
He died in 2018 at age 98. The record that can be confirmed here points to a career shaped by teaching, field biology, and practical, research-based writing about wildlife.
