Denis O’Connor, 73

Nov. 17, 1941-May 14, 2015

Denis J. O’Connor, who traded a long career as a corporate accountant in New York City for the life of a Montauk fisherman, died on May 14 after suffering a stroke. Mr. O’Connor, who had moved recently to Port Charlotte, Fla., was 73.

Born in Manhattan on Nov. 17, 1941, to Dennis O’Connor and the former Euphemia Caron, he grew up and went to school there before graduating from a boarding school in Boston. At Pace University in New York City he studied accounting and soon became a certified public accountant. He was hired almost immediately after by the Texas Gulf Mining Corporation, where he worked as a C.P.A. for about 20 years.

He was living in Staten Island in 1975 when he decided to move to Montauk, where he began working as a commercial fisherman. He worked with his son, Brian O’Connor of Montauk, for about 10 years, fishing for tuna and other saltwater fish, before becoming a mate on the charter boat Abracadabra.

His son said that even as Mr. O’Connor worked as a fisherman, he continued to perform accounting work for clients on the East End. “He was good with numbers,” said his son. In his spare time, he said, his father loved playing softball and rooting for New York’s sports teams. “He was a jolly person, friendly and fun to be with,” he said.

Mr. O’Connor was in the Army Reserves as a young man, stationed in Fort Dix, N.J. In Montauk, he was a member of the Friends of Erin.

He was married three times, first to Myrna Ramirez and then to Linda Riach. He is survived by his third wife, Darlene Berkhofer. In addition to his son and his wife, he leaves a daughter, Denise O’Connor Greenfield of Staten Island.

Two brothers and a sister survive as well. They are Joseph O’Connor of Montauk, John O’Connor of East Hampton, and Maureen Pierce of Michigan. He also leaves four stepsons, Raphel Riach of Saratoga, N.Y., Keith Berkhofer of Montauk, Tony Berkhofer of Montauk, and Wayne Berkhofer of Florida, and five grandchildren.

Funeral services were held on May 23 at the Kingdom Hall in Water Mill. A memorial wreath for Mr. O’Connor will be sent into the waters off Block Island Sound on Sunday during the annual Blessing of the Fleet. His ashes will be dispersed on the afternoon of July 12 from the Viking Star, followed by a gathering in celebration of his life at his son’s house.

Memorial contributions may be made to the East End Foundation, P.O. Box 1746, Montauk 11954, or to the Montauk Fire Department Ambulance Corps, 12 Flamingo Avenue, Montauk 11954.
