Grossinger's Catskill Resort Hotel was a resort in the Catskill Mountains in the Town of Liberty, near the village of Liberty, New York. One of the largest Borscht Belt resorts, it was a kosher establishment that catered primarily to Jewish clients from New York City. After decades of activity and notable guests, it closed its doors in 1986.
Asher Selig Grossinger moved from New York City to Ferndale in Sullivan County in the Catskill Mountains in the 1900s. There he rented rooms to visitors from New York City. His wife, Malka, operated the kosher kitchen, and Jennie Grossinger (1891–1972), his daughter, was the hostess. They called their home Longbrook House. In 1919, they sold it and purchased a bigger house on 100 acres (0.40 km2), calling it Grossinger's Terrace Hill House.
In 1952, Grossinger's earned a place in the history of skiing as the first resort in the world to use artificial snow. Reportedly, the Grossinger family offered a million dollars to rename the local New York, Ontario and Western Railway train station at Ferndale, NY to Grossingers, but were rebuffed by competing hoteliers.
By the time Jennie died in 1972, the hotel had grown to 35 buildings on 1,200 acres (4.9 km2) that served 150,000 guests a year. It had its own airstrip and post office. During his fighting days Rocky Marciano would train at the resort. But in the late 1970s and 1980s, resorts like Grossinger's or the Concord could no longer attract younger guests.
In August 1984, Grossinger’s, in its dying years, promoted a weekend to mark the 15th anniversary of the festival. It featured a workshop in tie-dyeing, a musical performance by David-Clayton Thomas, formerly of Blood, Sweat & Tears, a midnight showing of the four-hour documentary and an appearance by John Sebastian, who advised, "Don't eat the purple tzimmes."Abbie Hoffman, who was thrown off the Woodstock stage by Pete Townshend of The Who for making a political speech, was brought in by Grossinger’s for the promotion.
