Margaret Goff Clark was born March 7, 1913, in Oklahoma City, USA. At five, she and her family moved to Olean, New York. She attended Columbia University and State University in Buffalo, earning a bachelor’s degree in education. She began writing when her children were young and published her first book, The Mystery Of Seneca Hill in 1961. As a result, Ms. Clark was adopted into the Seneca Indian tribe in 1962.
Many of her books are based on her experiences traveling to parks and nature areas by camping trailer. The Clarks had a cottage in Algonquin Park in Ontario, Canada, and Death At Their Heels was written in 1975, after visiting it one summer. Most recently, Ms. Clark wrote books about endangered species in Florida, including the manatee and the Florida black bear. Her 1993 book on the endangered Florida panther was dedicated to her husband Charles R. Clark. In addition to books, Ms. Clark contributed over 200 short stories to magazines such as American Girl, The Instructor, Teen Talk and other Canadian and American magazines. Margaret Goff Clark passed away in 2003.
