"It's also philanthropic," said his wife, the former Sally Wistar Winsor. "The society raises money for members who may have fallen on hard times."
Before retiring in 1988, Mr. Miller, of Bryn Mawr, was an international reinsurance executive. Reinsurance is an agreement under which two companies agree to share exposure to risk.
For 30 years, he worked for Towers Perrin, now Towers Watson. Before that, he was employed by the Insurance Co. of North America and Marsh & McLennan Cos.
Born at Bryn Mawr Hospital in 1928, he moved to Oxford, England, as a boy when his father, an Egyptologist at the University of Pennsylvania, was invited to teach at Oxford University.
The family remained there during World War II, including the London Blitz.
Following military service, he earned his bachelor's degree at Trinity College, Dublin, Ireland. Mr. Miller returned to Philadelphia in 1952 to begin his career in reinsurance.
During this time, he met his future wife. The two wed in Bryn Mawr on Sept. 13, 1958, and were together for almost 55 years.
After retiring, Mr. Miller volunteered at Bryn Mawr Hospital, which was founded by his great-uncle George S. Gerhard. The George S. Gerhard Society, created in 1979, helps raise money for the hospital.
He and his wife traveled widely. In addition to the Society of the Cincinnati, he was a member of the Philadelphia Club, the First Troop Philadelphia City Cavalry, and the Merion Cricket Club.
For years, Mr. Miller supported the Philadelphia Orchestra and the Eagles. He was a student of history and the theater on Broadway and in London, and loved tennis, squash, and time spent with family.
Besides his wife, he is survived by sons Philippus III and Caleb North; a brother; and a sister.
Services will be at 3 p.m. Saturday, Sept. 21, at the Church of the Redeemer, 230 Pennswood Rd., Bryn Mawr. Burial is private.
Donations may be made to the Leukemia and Lymphoma Society, 555 E. North Lane, Suite 5010, Conshohocken, Pa. 19428.
