John Struthers Dunn Jr., 82, formerly of Moorestown, a retired company president, died of complications of chronic obstructive pulmonary disease, Saturday, May 28, at Kindred Hospital in Melbourne, Fla.

When he was 12, Mr. Dunn began working part-time for Struthers-Dunn, a manufacturing company his father, John Sr., established in Philadelphia in 1923. After he became president in the 1950s, he moved the company to Pitman. He retired in 1986. Struthers-Dunn produces electrical components used in the auto, defense, and aviation industries, and is now in South Carolina.

Mr. Dunn graduated from Germantown Friends School. He earned a bachelor's degree in management engineering from Rensselaer Polytechnic Institute and a bachelor's degree in mathematics from the University of Pennsylvania.

Since 1953, he had been married to Judy Perkins Dunn. They met growing up in Chestnut Hill. They raised a family in Camden and Burlington Counties and have a summer cottage in Strathmere, N.J.

An enthusiastic surfer, Mr. Dunn taught his children to surf at the Jersey Shore. They surfed in South Africa, the South Pacific, and on winter vacations in Puerto Rico for 40 years. He surfed until he was 70, his wife said.

When Mr. Dunn was with Struthers-Dunn, his wife sometimes accompanied him to Japan, where he went three times a year on business.

Mr. Dunn served on the boards of the Davidson School in Media and Children's Seashore House at Children's Hospital of Philadelphia. He was member of the Racquet Club of Philadelphia, the Merion Cricket Club, and the Moorings Club in Vero Beach, Fla., where he and his wife lived for the last 15 years.
