A Brooklyn Polytechnic-educated engineer, Martin Ligorner served in the Army Corps of Engineers in the 1950s, stationed in Alaska and Germany, and later had a long career with General Electric.
Here on the South Fork, living in Amagansett first by renting a small house before buying in 1986, Mr. Ligorner took up selling real estate with Douglas Elliman. He was the founder and former president of the East End Dunes Residents Association and was considered “the unofficial mayor of Napeague,” his family said.
Mr. Ligorner, who most recently lived in Northampton, Mass., died at a memory care facility there on July 9. He was 89 and had dementia.
“He was the eternal optimist, and he loved family and community,” one of his daughters, Sharon Ligorner Castelli of Northampton, said.
He took up tennis and golf late in life, and was a member of the South Fork Country Club. He enjoyed talking about business news and current events. A car enthusiast, he had worked for a time at car dealerships in the Bronx.
In October 1982, he married Toby Schlosberg, who survives and continues to live in Northampton.
Martin Maurice Ligorner was born in Brooklyn on Dec. 25, 1934, to Samuel Ligorner and the former Rose Bloch, and grew up there.
In addition to his wife and daughter, he leaves another daughter, K. Lesli Ligorner Ritchie of Tokyo. A brother, Allen Ligorner of Edgewater, N.J., and two grandchildren also survive.
A memorial service was held on Friday in Chesterfield, Mass. Mr. Ligorner’s family has suggested memorial donations to a GoFundMe page in support of friends overseas who are relocating to a safe country, online at gofund.me/a4a1697c.
