Mercer Logan Stockell, a prominent trademark attorney, died of cancer in his Glen Cove home on Nov. 23. He was 91.
Stockell had been a senior partner at the Manhattan law firms of Rogers Hoge & Hills and Pennie & Edmonds, both now shuttered.
"For close to 50 years, he represented many of the most prominent brands of his time, including IBM, Texaco, Black & Decker, Bacardi, American Tobacco, Swingline, Master Lock . . . AMF and Titleist," said his daughter, Catherine Bannon, of North Salem and Manhattan.
A longtime member of the International Trademark Association, he was highly influential in the development of this area of law.
His daughter said he was a mentor to many young trademark practitioners over the years, including herself and nephew William Pecau.
"He was one of the most prominent trademark attorneys of his time," said Pecau, who grew up in Glen Cove but now lives in the Washington, D.C., area.
"He was the straightest shooter I had ever known. If he said it, you could take it to the bank. And he was the kind of guy who helped numerous people but never talked about it."
A native of Nashville, Tenn., Stockell graduated in 1943 from Sewanee: The University of the South, in Sewanee, Tenn., with an economics degree.
He immediately enlisted in the Marine Corps, his family said. He became a captain and fought in numerous battles, including the Battle of Peleliu, which had the highest casualty rate for U.S. military personnel of any battle in the Pacific during World War II.
After the war, he went to Harvard Law School, graduating in 1948.
He retired in 1995 to care for his wife, Eliane Grignard Stockell, who had developed cancer. They had been married for 47 years and were longtime members of St. John's of Lattingtown in Locust Valley.
After his wife's death in September 1997, he devoted himself to family, travel around the nation and the world, and history, especially of his ancestry, said his daughter.
"On his mother's side, the family went back to the Colonial settlement of Jamestown, in Virginia. On his father's side, the family goes back to the War of 1812," she said. "He enjoyed documenting it for his descendants."
Other survivors are two sons, Mercer Jr., of Glen Cove, and Albert, of Nairobi, Kenya; and six grandchildren.
Services were held at St. John's, and burial was in the church's Memorial Garden.
