John Sadowsky Jr.

John Sadowsky Jr., who at one time managed East Hampton Bowl, died on Aug. 6 at home in Onancock, Va. He was 75. The cause of death was liver disease, his family said.

Mr. Sadowsky was born on Dec. 18, 1938, at Southampton Hospital, to John Paul Sadowsky and the former Antonia Wazlo. He grew up in East Hampton, graduating from East Hampton High School.

He was in the United States Navy for two years, stationed in Virginia. He then worked for Grumman Aircraft before becoming the manager of the East Hampton bowling lanes.

Moving on, he went into business for himself as a contractor and builder. In the mid-1990s, he built a waterfront house in Virginia and moved there to live shortly after. He worked until his illness was diagnosed, about a month before his death.

His family said he loved the blackjack tables at the Harrington, Del., and Atlantic City casinos. Other interests included “fast cars, furniture-making, gardening, and spending long holidays with his children here in East Hampton.”

Mr. Sadowsky’s first marriage, to Phyllis Dellgren of East Hampton, ended in divorce. They were married from 1960 to 1975. His partner of 25 years, Mary Alice Condon, died in 2011.

Three daughters and a son survive. They are Barbara Lester of East Hampton, John W. Sadowsky of Sagaponack, Donna Vorpahl of East Hampton, and Heidi Cavallo of Southold. He leaves nine grandchildren and one great-grandchild.

Mr. Sadowsky had been a member of Most Holy Trinity Catholic Church in East Hampton. His ashes will be buried in the church cemetery in the fall.

Memorial donations have been suggested to Hospice and Palliative Care of the Eastern Shore, 165 Market Street, Suite 3, Onancock, Va. 23417.
