Frank Secor Dickerson, III died on August 29, 2026, in Duxbury, Massachusetts. He was 87 years old. Known as Skip since his early childhood, he was born on June 19, 1939, in Ithaca, NY. Skip was the son of the late Mary Louis Pierson Dickerson and the late Frank S. Dickerson, Jr.

Skip is survived by his children, Wendy Dickerson of Wheatland, Wyoming, his son, David, of Freising, Germany, and his grandson, Kevin, of Freising, Germany. He is also survived by his 3 stepchildren and their families: Michele Hunter and her husband, James, of Windermere, FL and their children, Jay, Patrick and Andrew; Roy (“Scott”) Parker and his wife, Tanya, of Silver Spring, MD and their children, Talia and Noah; and Brooks Day and her husband, Tom, of Millis, MA and their children, Finian, Treasa and Brayden. He is also survived by his brother-in-law, Peter Swanson, and his children, Eric and Bradford. Skip was predeceased by his wife of 41 years, Lynda Dickerson (Stucker), his sister, Ann Dickerson Swanson, and his first wife, Leslie Dickerson.

Skip spent his early childhood in Longmeadow, Lexington, and Concord, Massachusetts. He graduated from Governor Dummer Academy (now The Governors Academy) in 1957, following which he attended the Forest School in London, England for one year on an English Speaking Union exchange scholarship. Skip graduated from Amherst College in 1962, where he majored in biology.

After Amherst, Skip worked for one year in the management training program of the First National Bank of Boston before attending the University of Michigan Law School. In his final year at Michigan, he served as an editor of the Michigan Law Review. Upon graduation with his Juris Doctor degree in 1966, Skip began his legal career with the law firm of Cravath, Swaine and Moore in New York City as an associate attorney.

In 1973, Skip joined the law department of Bethlehem Steel Corporation in Bethlehem, Pennsylvania where he rose to be Assistant General Counsel and Assistant Secretary. In 1983, Skip was elected Vice President and Treasurer of Bethlehem and attended the Advanced Management Program at the Harvard University Business School in 1984. Skip became Senior Vice President and Chief Financial Officer of Mapco, Inc. which was headquartered in Tulsa, OK in 1987. In his role at Mapco, Skip had management responsibility for the Accounting, Treasury, Audit, Information Systems, Tax, Purchasing, Strategic Planning, Risk Management, and Credit functions of the Company. He also served as a member of the Senior Management Committee.

During his legal and business career, Skip was active in numerous professional and cultural organizations and served on a number of not-for-profit boards and committees. Among those, he was a member of the Board of Governors of the American Red Cross from 1989 to 1995, serving on its Executive, Audit, Chapter Relations, and Finance Committees. He chaired the Audit Committee for 3 years and the Finance Committee for 2 years.

Skip and his family have had roots in Truro, Massachusetts on Cape Cod since the late 1920s. So, it became natural for Skip and his wife, Lynda, to relocate to Truro in 1998, having summered there for a number of years before that. To avoid the snow and cold of New England, Skip and Lynda spent almost 17 years wintering in San Pancho, Nayarit, Mexico, finally building their own home there in 2007. In 2011 Skip and Lynda relocated to The Village at Duxbury, a senior retirement community in Duxbury, MA, where Skip served on the Board of Directors, the Budget and Finance Committee, the Capital Planning Committee, and a number of Board advisory groups. Upon the sale of their treasured Mexican property and later, their Truro property, they settled into their Duxbury home full-time.

Skip was never comfortable just sitting around, so when not busy with his business and family commitments, Skip tried hard to maintain his physical health from his soccer and lacrosse playing days by enjoying tennis, biking, cross-country skiing, hiking, and fitness centers. Those activities were augmented by his love of house maintenance and landscaping projects.
