Glenn Crawley Ziegler, 87, of Wilton, Connecticut and Bozeman, Montana died at dawn on September 11, 2013 at her ranch northeast of Bozeman.

Glenn was born in New York City and brought up there and in Southampton, New York. In New York City she attended what is now The Hewitt School. She graduated from Wellesley College and became a book buyer for B. Altman & Co. In 1950 she married William A. Ziegler, an associate and later partner of Sullivan & Cromwell, the New York City law firm.

Surviving Glenn are her husband, her four children, Richard S. Ziegler of Wilton, Daryl A. Henning of Bozeman, Susan G. Barrows of Bozeman and W. Thomas Ziegler of Dorset, Vermont, six grandchildren, two great-grandchildren and a sister, Jeanne Macero of Quogue, New York. Glenn was predeceased by her parents, Mr. and Mrs. Charles E. Crawley of New York City and Southampton.

Glenn and Bill moved from New York City to Darien, Connecticut in 1957. In 1989 they acquired their ranch near Bozeman. It was for them their second home. In 1994 they moved from Darien to Wilton.

Glenn loved animals. At the ranch, where she spent half the year, she kept animals only as pets.  They included horses, goats and donkeys large and small. During her life she was always surrounded by adopted dogs and cats — even a monkey and a pair of flying squirrels. In Bozeman she rescued injured animals and birds of all sorts and, on their recovery, assisted in returning them to the wild.

Glenn was the first Treasurer of what is now known as The Raptor Conservation Center in Bozeman. She enjoyed annual trips to Yellowstone Park, particularly to the Lamar Valley, which was her favorite destination there. Glenn loved to travel to exotic places to observe the animals native to those locations. Her trips, largely with the New York Zoological Society and The National Audubon Society, took her to, among other places, Borneo, India, Nepal, Sri Lanka, Thailand, Brazil, Ecuador, Peru, Argentina, Australia, New Caledonia, Kenya, Tanzania, Hawaii and Alaska.

She was an active volunteer at The Ox Ridge Hunt Club in Darien, accompanying her children and others to horse shows throughout New England, and in connection with the annual horse show that took place on the Ox Ridge grounds. Her favorite television program was, on nights she did not attend in person, the Westminster Kennel Club annual dog show. Glenn was also an avid reader.  Mystery stories were her favorites. She liked to instill her fondness for reading in children and for years was a school librarian in Darien.

Glenn will forever be loved and missed by family and friends.

Funeral arrangements were private.
