Helen T. Armstrong, a retired public school librarian, died June 21 of multiple organ failure at Kendal at Longwood retirement community in Kennett Square, Pa.
She was 95.
Helen Towne Armstrong, the daughter of James Wadsworth Armstrong and Abbie Richmond Armstrong, was born in Baltimore and was raised in a house on the grounds of the Lake Montebello filtration plant, which her father had designed and managed for 25 years.
He also designed the dams at Prettyboy and Loch Raven reservoirs, said a niece, Martha Hendrickson of Lutherville.
"She had many fond memories of growing up at the plant," said Ms. Hendrickson. "She said it was like living in a park. The plant and house they lived in was located in an idyllic setting and was planted with many trees and flowering shrubs. There were patches of woods, a pond, and close to Lake Montebello and Herring Run."
After graduating from Eastern High School in 1934, she earned a bachelor's degree in 1938 from what is now McDaniel College. In 1939, she earned a bachelor's degree in library science from the University of North Carolina.
She lived in Bradenton, Fla., for several years where her father had moved after retiring in 1937. She went to work in 1942 as a librarian at the University of Maryland, College Park and six years later joined the public library in Tacoma, Wash., as head of the young people's division.
Miss Armstrong held library positions in Tallahassee, Fla., and in 1953, joined the Philadelphia Public Library and later served as head of its children's division.
In the 1970s, she moved to Vineland, N.J.,. where she was a public school librarian. She retired in 1987 and moved to the retirement community in 1989.
She had been a member of Eutaw United Methodist Church in Baltimore, and was a member of West Chester United Methodist Church in Pennsylvania.
Miss Armstrong was a world traveler, avid reader, painter and writer. She was also a cat fancier.
A memorial service will be held at 2 p.m. July 21 at the retirement community, 1109 E. Baltimore Pike, Kennett Square.
Miss Armstrong is survived by other nieces and nephews; and many great-nieces and great-nephews.
