AUBURN – Philip Earhart Guiles, 74, of New Gloucester, died on Nov. 24, at the Hospice House in Auburn.

He was born in Boston, Mass., on Nov. 29, 1931, to Austin Philip Guiles and Louise Earhart Guiles and grew up in Newton, Mass., where his father was on the faculty of the Andover-Newton Theological Seminary.

He attended Deerfield Academy, graduating in 1950, and attended Princeton University for two years before enlisting in the army. He was trained as a language specialist and stationed in Germany.

Following three years of military service, he enrolled at Colby College in Waterville. Elected to Phi Beta Kappa, he graduated with a degree in business administration in 1958.

While at Colby, he married his first wife and subsequently became the father of four children. Following graduation, the family moved to Ann Arbor, Mich., where he worked in several positions in farm and asset management and aviation insurance.

In 1969 he moved to Yarmouth, where he lived for the next 19 years. There, he focused on his proudest achievement, the raising of his children. To this end, he was active in the Boy Scouts, Little League, and other activities in his children’s lives.

He was also an active member the First Parish Congregational Church of Yarmouth. The possessor of a fine bass voice, he especially enjoyed singing both in the church choir and with the Choral Arts Society of Portland.

He also served on a statewide citizens advisory board for the then Bureau of Mental Retardation.In 1988, he moved to New Gloucester and married Catharine D. Wilder, formerly of New Haven, Conn.

There, he became a supporter of Opportunity Farm and joined its board of trustees, serving on several committees and becoming the chairman of the board for three years at a time when the farm’s leaders were developing a strategic plan and initiating an ultimately successful capital campaign for its new campus for girls.

He was a family member of the Earhart Foundation, based in Ann Arbor, from 1969 until his death. The chief mission of the foundation, founded by his grandfather, is the support, through grants to scholars and institutions, of the advanced study of political science, economics, and related disciplines.

Like his father, he took a great interest in vintage cars, planes, and motorcycles. During his high-school years, he rebuilt a 1928 Ford Model A, and during the time he lived in Michigan, he owned and flew a 1936 Waco YQC-6 (April model) and a 1936 Ryan STA.

After he moved to New Gloucester, he revived this hobby, acquiring and rebuilding Indian motorcycles. With this interest, he became an active participant in antique motorcycle organizations.

He is survived by his beloved wife, Catharine; and by his four children, Richard E. Guiles of Portland, Austin P. Guiles II and his wife, Elsbeth W. Guiles, of Chapel Hill, N.C., Ethan S. Guiles, of Montpelier, Vt., and Pamela M. E. Guiles, of Scarborough.

He is also survived by his two sisters, Gwyneth G. Webb and her husband, Paul, of Helen, Ga., and Marian G. Schmidt and her husband, James, of Rome; his brother, Jeremy S. Guiles and his wife Cynthia, of Sarasota, Fla.; twelve nieces and nephews; and many great-nieces and great-nephews.

He will be deeply missed by all his family and close friends, among them Paul and Dartha Reid, of Lamoine; and Paul Flynn, of New Gloucester and Lake Wales, Fla.
