HOLLY FARM to MENDEL: (c. 1907)
One of South Plainfield’s first large-scale residential developments began with Milton Mendel’s purchase of John I. Holly’s 100-acre farm off Park Avenue around 1907. It appeared to be a sound investment by the New York lawyer who was attracted to Plainfield and its suburbs for much the same reasons as Holly and many wealthy Wall Street financiers and industrialists. Known as “The Queen City,” Plainfield was a thriving resort destination whose scenic countryside and healthy climate — promoted by a local newspaper publisher as the “Colorado of the East” — drew businessmen, their families, and developers for weekend visits and summer stays, often inspiring the construction of both grand estates and smaller seasonal homes.
In 1908, Mendel and Elk Realty issued a plat map illustrating how Holly Park would be divided into lots, blocks, and streets. Advertisements directed at “nerve-tired” New Yorkers seeking quiet summer retreats in the country touted “artistically built bungalows with steam heat, bath and every modern convenience, wide porches, and open fireplaces for $2,500 upwards. Pay like rent -- $30 monthly.” Amenities included unrestricted use of Holly Lake for boating, swimming, fishing, and skating, with access to club stables in the near future. The bungalow colony was close to Plainfield Country Club Golf Links and passenger train service on the Lehigh Valley and Central Jersey. Mendel pledged to preserve the area’s natural beauty in a parklike setting while providing modern conveniences, including gas, electricity, and water.
Excluded from development plans were Holly Lake and the 18-room Holly farmhouse that Mendel shared with his parents, Gustav and Nettie, and one or two servants on (West) Crescent Parkway. Gustav, a German native, immigrated to the United States at age 14 and settled in Cincinnati for 50 years. During the Civil War, he prospered as a manufacturer of Union Army uniforms. After the war, he founded Corbin, Mendel & Co., a wholesale liquor firm, and Mendel & Co., makers of high-end wardrobe trunks. The family moved to New York in 1896, and to South Plainfield with the purchase of property.
Published real estate transactions reported to local newspapers by Middlesex County suggest that sales of Holly Park lots were initially slow. During this period, Mendel also pursued other ventures both civic and business, though some are difficult to date precisely.
HOLLY LAKE
In 1917, the Plainfield Courier-News called Holly Park “an embryonic Atlantic City.” Over several years, Mendel had turned the small, shallow, spring-fed lake behind the homestead into a popular recreation spot for swimming. Originally kept for the enjoyment of John I. Holly’s four children in the 1890s, the lake in 1915 attracted hundreds of paying visitors, many from outside the area. As its popularity soared, Mendel grew concerned that the lake was too small for the increasing numbers of patrons, causing him to limit access to those he knew while closing it to the general public.
Two years later, Holly Park Bathing Beach reopened to the public after Mendel’s most ambitious renovation was completed. The lake had been drained, cleaned, and expanded to nine acres to accommodate more patrons and its depth increased gradually toward the center to support a planned diving platform. Hundreds of wagonloads of sand had been spread across the lakebed and banks to give it the appearance of a seaside resort. Mendel also added fifty rental bathhouses, a refreshment stand, and electric lights for evening swimming. Admission was 15 cents for adults and 10 cents for children on weekdays, increasing to 25 cents and 15 cents on weekends and holidays. The Suburban Transit Company ran buses from Proctor’s Theater in Plainfield on both weekdays and weekends. Under Mendel’s management, the operation was highly successful and continued to attract hundreds of summer visitors.
Mendel leased the bathing beach concession to George Blair in 1920, then to the Keiler brothers in 1923. Creative promoters, they attracted not only swimmers but also visitors looking for other forms of entertainment, adding a merry-go-round, pony rides, water slides and a dance pavilion where large crowds of young people Charlestoned the night away with Allie Maiden and the Syncopators performing. They also built a new road over the old dam in the middle lake, giving cars access from Maple Avenue to the amusement area on the south side.
Some events attracted thousands of spectators, including the 1926 Mardi Gras festival, which featured a bathing beauty contest, swimming and diving exhibitions, lifeguard demonstrations, fireworks, dancing, and music from 1 p.m. to midnight. On another occasion, a daredevil pilot staged aerial stunts over the lake, even skimming the water with the plane’s wheels.
The crowds drawn to Holly Park’s attractions — especially the dance pavilion — were not universally welcomed. Neighbors brought their concerns to the Borough Council twice; the first time, Councilman Mendel — himself an elected member from 1926-29 — heard the complaints firsthand. The Keilers’ lease, set to expire in the fall of 1927, was not renewed, and the structures they had added, including the dance pavilion and cabanas, were removed.
Mendel kept the beach open in 1928, but swimming ended in 1929 after the cement bridge at the far end of the lake collapsed, draining water into Spring Lake. In 1930, residents asked the Borough Council to regulate amusement venues before Mendel could lease the site again. The Council passed a resolution and instructed borough attorney Andrew L. McDonough to draft an ordinance regulating such places. Holly Park Bathing Beach closed permanently. Mendel and his wife, Eunice, operated Holly Park Midget Golf Links at Park and Maple from 1930 to 1931, after which it disappeared from the public record.
CAMP HOLLY
When the United States entered World War I on April 6, 1917, officials feared food shortages as farmworkers left for military service. New Jersey responded by urging residents to grow food at home so more could be sent overseas. Later that month, Plainfield launched Camp Holly on more than 70 acres of idle South Plainfield farmland at Holly Park, funded by a $5,000 private donation. Teaming up with Plainfield and North Plainfield High School for labor, the Boy Scouts of America for structure, and Milton Mendel for the use of Holly Farm, “Camp Holly” on (West) Crescent Parkway would be hailed as “one of the largest agricultural propositions using boy labor in the United States.”
Boys 14 and older in good academic standing were eligible to participate in the war garden project and live at Camp Holly for the growing season. The Boy Scouts managed the camp, Rutgers-trained farm supervisors ran operations, and the Plainfield Board of Health oversaw sanitation. Campers received room, board, a share of profits, and one dollar a week for up to eight hours of work a day, five days a week. They lived in tents and ate communally. For recreation, Mendel allowed them to use Holly Lake for fishing, swimming, and boating. Later, a house on the property was rented from Mendel and served as a recreation center.
The first boys arrived in May when planting began, with more joining through June. All received practical farm training. By May 25, the first 15 acres were planted as Woodbrook Farm’s rented steam tractors continued to plow and fertilize further acreage. At the end of July, Camp Holly’s first crop of beans, peas, cucumbers, beets, and other veggies went on sale at Boy Scout Headquarters on Front Street in Plainfield. As the growing season progressed, the boys harvested cantaloupes, watermelons, bush limas, potatoes, cabbage, carrots, tomatoes, field corn, sweet corn, and winter squash that drew praise from agricultural experts.
The camp closed in early October after a large bean harvest involving 200 boys. Although Camp Holly was not revived in 1918, it reflected the broader home-front effort and Milton Mendel’s generosity that turned idle land into food production during World War I.
LAKESIDE HAVEN OF REST
Mendel’s Lakeside Haven of Rest presents a puzzling timeline and the unrealized promise of an intriguing business venture. He intended to convert part of the 18-room homestead into a quiet country retreat for weary city residents.
A small brochure was produced for distribution describing Plainfield’s easy access by train from New York and its location just beyond the city line. Prospective clients were reminded of the city’s clean air and invigorating climate that helped it earn the nickname “the Colorado of the East.” Few towns could rival its pure air, good water, and attractive scenery—qualities believed to restore health and relieve stress and fatigue.
The Haven promised abundant opportunities for open-air living. Set beside a clear, nine-acre spring-fed lake and surrounded by broad lawns, mature shade trees, and sunny verandas, it offered an especially appealing outdoor setting. Business and professional men and women seeking rest would find it an ideal weekend retreat for boating and bass fishing.
The interior was designed to match the appeal of the grounds, with inviting reception areas and private rooms. Bright, comfortably furnished spaces created a restful, home-like atmosphere and included electric lighting, telephone service, and call bells to summon nurses when needed.
Guests were promised attentive care and, when necessary, access to visiting physicians or the option to consult their own doctor. The Haven was equipped to care for guests with nervous or heart conditions, convalescents, and others needing rest or a special diet. It also offered full maternity care, including the option of the then-new twilight sleep method. Electric baths, massage, and vibratory treatments were available.
Rates ranged from $25.00 to $60.00, with special treatments priced according to individual needs.
Apart from its promotional brochure, the Lakeside Haven of Rest appears to have left no discernible trace in local memory or newspaper coverage. In practical terms, it existed only as a proposal. The retreat never opened, apparently because Mendel was unable to secure the necessary staff. Carmen Helmer Smith, Mendel’s sister-in-law, confirmed that the spa was never established.
The remaining question is when was this proposed? One clue appears in the brochure: Mendel describes the lake as nine acres. It was enlarged to that size in 1917. However, it seems unlikely that people seeking rest and relaxation would have shared the setting with hundreds of noisy visitors at Holly Park Bathing Beach.
AMERICAN SILVER CO. to MENDEL: Driving Park/Fairground (May 1911)
The sale of the Plainfield Driving Park/county fairgrounds to Milton Mendel in the spring of 1911 marked the end of a venerable and beloved institution begun in the 1860s. The 35-acre plot extending from Park to Woodland Avenue facing the Plainfield Country Club was slated for residential development in the near future, but Mendel allowed racing and other activities to continue.
MENDEL to HOLLY CREST REALTY: Driving Park/Fairgrounds (August 1911)
In August, Mendel transferred the same property to Holly Crest Realty Co. of New York, led by J.B. Schwabacher. Activities at the park continued through most of 1912. In November the barns, grandstand, judges’ stand, and fencing were offered for sale for immediate removal. A plat dated November 12, 1912, outlined the layout of lots, blocks, and streets for Holly Crest.
Schwabacher would soon form Avon Park Realty Corporation and purchase the property north of Holly Crest to Maple Avenue between Woodland and Park Avenues. By the beginning of 1919, contractors were grading and cutting streets in Avon Park.
South Plainfield was in a housing boom.
