In the 1970s, Jean Lindgren would proudly point out that she was the first woman carpenter on the South Fork. She had the shoulders and biceps to match, too.
This was after a stint teaching nursery school at the Hampton Day School in Bridgehampton, where she met Anthony Hitchcock, a science teacher with whom she would go on to work an array of odd jobs, at a time here when it was far easier to get by that way. This involved building greenhouses, in an elaborate process of gluing and clamping to bend wood supports, done in a barn behind their rented farmhouse in Bridgehampton, catering, notably the wedding of the sportswriter Mike Lupica, with attendees ranging from Don Imus, the radio host, to Donald Trump, and writing a series of guide books to country inns and historic hotels.
The job that wound up truly lasting, however, came about when Ms. Lindgren and Mr. Hitchcock took over the logistics for a small local horse show at the Topping Horse Farm in Sagaponack. As this area became more popular, more of a destination, more characterized by celebrity, so did the show, which in 1977 came to be known as the Hampton Classic, first at Dune Alpin Farm in East Hampton and then on 65 acres in Bridgehampton. The two ran it as a benefit for Southampton Hospital until 2005.
Ms. Lindgren, who lived in Sagaponack, died of heart disease on May 27 at Peconic Bay Medical Center in Riverhead. She was 85.
The Hampton Classic may have been fancy, but the co-executive directors, who were not riders themselves, made certain to allow for the equestrians and fans from the area, introducing Local Day and accommodating Bridgehampton families like the McCoys and the Brennans with tables in the Grand Prix tent.
In many ways the face of the show, working with participants and registrants, the aggrieved and the entitled, Ms. Lindgren was invariably cheerful and charming, with a sense of humor that could defuse any misunderstanding.
Born on March 4, 1941, in Tenafly, N.J., the eldest of four children of Robert Lindgren, a commercial illustrator, and the former Ruth Jaster, she grew up across the New York border in Suffern, where the family had a horse rescued on its way to becoming mink food and an old jalopy she learned to drive before she was a teenager.
She attended Mary Washington College in Virginia but left before graduating, and later married Peter Greene, whom she knew from Suffern High School. They had two children. The marriage ended in divorce, but not before they moved to Sag Harbor in 1969.
In the mid-1970s, in Bridgehampton with Mr. Hitchcock, whom she would marry in the 1990s, the two were known for their volunteer work, particularly with the local historical society and the Black community of the Turnpike, at one point installing a small steeple atop the Baptist church, which led to a story they liked to tell of the difficulty of compound angles.
In later years, after the Hampton Classic, Ms. Lindgren continued to work as a secretary on the horse show circuit, from Westchester County to Ocala, Fla., to Indio, Calif., and she and Mr. Hitchcock began to vacation here and abroad, to France every spring, to Maine at the end of every summer.
Painting was one of her pastimes, and her children and grandchildren always looked forward to the cartoons she would draw for their birthday cards. She enjoyed mystery novels, watching “Jeopardy!” and “Antiques Roadshow,” shopping trips with her granddaughters, and baking, especially Christmas cookies.
Mr. Hitchcock survives her, as does a stepdaughter, Abigail Hitchcock of Brooklyn, two sons, Ryder Greene of Portland, Ore., and Baylis Greene of Noyac, a daughter-in-law, Julie Greene, and three grandchildren, Penelope, Griffin, and Bennett Greene. She also leaves a sister, Patricia Lindgren of Cold Spring, N.Y. Her brothers, Robert (Bud) Lindgren and Carl Lindgren, died before her.
A celebration of her life is scheduled for Aug. 6 from 6 to 8 p.m. at Long Beach in Noyac.
