Environmentalist and civic leader Ann Simms Stubenberg, who died July 2, will be honored by The Outdoor Circle on Sept. 14 with the planting of a monkeypod tree in her memory on Sand Island.

Stubenberg was a former president of the organization.

During her many years as a member of the Outdoor Circle, Stubenberg often gave testimony before both the City Council and the state Legislature on environmental issues.

She served multiple terms as president of both the YWCA and The Outdoor Circle.

Stubenberg chaired the Punahou Carnival in 1962, served on the board of directors of the Bishop Museum and was active as a volunteer of the Friends of the Library at the 'Aina Haina branch.

"Few people cared as much for Hawai'i's scenic beauty as she did," said Mary Steiner, chief executive officer of The Outdoor Circle.

"Ann was a fierce advocate for keeping Hawai'i clean, green and beautiful. She instilled those strong values in the people around her and her legacy will continue to inspire us all."

Born Ann Simms on Sept. 4, 1921, in Los Angeles to architect James Simms and his wife, Florence, Stubenberg came with her family to Hawai'i in 1927 where her father entered the firm of architect C.W. Dickey.

His work included the Blaisdell Concert Hall.

She graduated from Roosevelt High School in 1939 and entered the University of Hawai'i as an art major.

After graduation, she became an oil painter and water colorist while developing friendships with other Hawai'i artists.

In 1943 she married Arthur Stubenberg, who became a leading player in the mechanization of the Hawai'i sugar industry.

Stubenberg is survived by sons James of Honolulu and David of Reno, Nev.; daughter Joanne of Kona; six grandchildren; two great-grandchildren, and a sister, Joan Bellinger of Honolulu, also 14 nieces and nephews.

A tent and refreshments will be provided at the tree planting in her honor.
