Robert Lachmann of Montauk and Longboat Key, Fla., a former co-owner of the Montauk I.G.A., Boathouse Restaurant, and Lido Motel, died of a heart attack at his summer residence in Montauk on July 1. He was 86.
Mr. Lachmann, who was called Bob, was born in New Rochelle, N.Y., on Oct. 28, 1935, to George Lachmann and the former Florence Weber. He attended the General Motors Institute in Flint, Mich., and served two years in the Army starting in 1958.
He moved to Montauk in 1970, and the following year, he met Margaret Burke. They were married in November 1980. She survives him, as do two sons, Robert Lachmann Jr. and William Lachmann of Waterville, N.Y., and a daughter, Jill Bryant of Clover, S.C. He leaves six grandchildren, Tiernan, William, John, and Luke Lachmann and Kyla and Olivia Bonikowski, and a step-granddaughter, Mindy Lachmann. A sister, Paula Hengel of Vero Beach, Fla., also survives. A stepson, Edward Skip Golden, died before him.
In 1980, the Lachmanns built the Boathouse Restaurant, now called Harvest on Fort Pond. He retired 27 years ago.
Mr. Lachmann loved antique cars and owned many over the years. He was an eager golfer and fisherman, and liked building models of wooden ships. He was a member of the Longboat Key Club for 35 years and was also active in the Montauk Chamber of Commerce. His wife said he will be remembered for his engaging personality and sense of humor.
Mr. Lachmann was cremated. Visiting hours will be next Thursday at the Yardley and Pino Funeral Home in East Hampton from 6 to 8 p.m. A celebration of his life will be held on Longboat Key in the fall. His family has suggested memorial donations to the Montauk Fire Department’s ambulance company at 12 Flamingo Avenue, Montauk 11954.
