Mary Gertrude Seiberling Huhn, a longtime social justice activist and Akron native, died Thursday night at her home in Berwyn, Pa., at age 98.

She was the daughter of J. Frederick and Henrietta Buckler Seiberling — who was an instrumental figure in the founding of Alcoholics Anonymous — and grew up at the Gate Lodge at the Stan Hywet Hall estate of her grandfather, Goodyear Tire & Rubber Co. co-founder F.A. Seiberling.

Her daughter, Mary Huhn, told the Beacon Journal that Seiberling Huhn enjoyed sharing memories of her childhood in Akron.

"It was a delight to hear her tales of growing up at Stan Hywet," Huhn said, "… from wandering among the orchards and playing the organ in the Great Hall — as well as the horses and yule log in the Great Hall at Christmas."

Mary Gertrude Seiberling was born Sept. 20, 1920. She attended Old Trail School in Bath before following in her mother's footsteps at Vassar College in Poughkeepsie, N.Y.

In December 1939, she presided as queen of the Rubber Ball at the Akron Armory, where an estimated 4,000 people gathered for the second annual grand celebration of the city's industry. A Beacon Journal photo of the event showed her alongside the ball's king, Leonard E. Firestone, one of the five sons of the late Harvey Firestone. It became the last of the galas as Akron busily swiveled to meet the heavy demand for rubber in World War II.

She graduated magna cum laude from Vassar in 1941 with a degree in English. She taught at Garrison Forest School in Owings Mills, Md., before moving to New York City, where she met George A. Huhn V. The two married there in 1951. They settled outside Philadelphia in Devon, Pa., in 1960.

Seiberling Huhn ardently took up antiwar, antinuclear and environmental causes and attended dozens of rallies in Washington from the 1960s onward. She attended her final rally in the nation's capital in 2013 at age 92, marching with the Sierra Club to raise awareness about global warming.

She loved literature, especially poetry, and all types of music. Her daughter noted that even in her final days, Seiberling Huhn was moved to quote her favorite works.

Her brother John F. Seiberling, two years older, shared her deep appreciation of nature and made the creation of what is now the Cuyahoga Valley National Park his greatest legacy as a longtime U.S. congressman representing the Akron area.

Seiberling Huhn also was a media junkie. Her sister Dorothy, two years younger, was a longtime art editor at Life magazine.

Among her other passions were organic gardening, animals and working to improve the world as a congregant of the Main Line Unitarian Church.

She is survived by her sister, Dorothy Seiberling Steinberg, and children George F. Huhn (Julie Brewer), Curtis Huhn (Cheryl Lynne Huhn), Mary Huhn (Jim Rich) and William Huhn (Julia Hines Huhn), along with eight grandchildren, eight great-grandchildren and three nephews.

A celebration of her life will take place at Main Line Unitarian Church later this year.

In lieu of flowers, donations can be made in her name to the B+ Foundation: A Children’s Cancer Charity, the Sierra Club or Old Trail School.
