Herbert Haucke, 84

Herbert Haucke of Montauk, a partner in an insurance firm in Manhattan that he built into a successful business, died on Feb. 1 at the Peconic Bay Medical Center in Riverhead after a fall. He was 84.

Mr. Haucke and a business associate and friend, Murray King, sold business liability insurance and other packages. They were also in a “mockumentary” produced by Leeam Lowin and Amram Nowak called “King Murray,” made in 1969. A friend and neighbor of Mr. Haucke’s at Windmill Village in East Hampton, Walter James Blumberg, wrote the blurb for the IMDb: “Murray King and Herbert Haucke are able to comfortably navigate the fine line between fiction and reality so convincingly you are able to better appreciate the confidence and intensity these men possess.”

“His ability to relate to people,” Mr. Blumberg said, “his comfort with presentation and public speaking, and his lack of fear and tenaciousness prepared him for the role he played as an over-the-top salesman who accompanied . . . Murray King on the trip to Las Vegas portrayed in the movie.” He said that the film won an award at the Edinburgh Film Festival.

Mr. Haucke was born in New York City on Sept. 18, 1933, and brought up by his mother after his father, Herbert Haucke Sr., who was a New York Police Department patrolman in the 103rd Precinct in Queens, was killed in the line of duty when his son was not even a year old. Herbert and his mother would visit a small family cottage in Montauk, and when she could not take him there, he would go on his own, camping at the beach at Camp Hero. He told Mr. Blumberg that he remembered seeing soldiers who were stationed there during World War II.

For many years, Mr. Haucke kept a powerboat in Montauk. He bought and sold houses for a time, Mr. Blumberg said, and about six years ago moved into Windmill Village.

Mr. Haucke will be cremated and his ashes dispersed by his friends. A memorial is being planned for a later date.
