I can only find two references for Schwartz’s Dairy at the Woodhaven Queens location.
Schwartz’s Model Dairy is listed in the 1915 NYC Telephone Directory located at Union Course Long Island. (Union Course was part of Woodhaven) The following year, on September 7, 1916 the following notice of incorporation appeared in the Brooklyn Daily Eagle:
Schwartz’s Dairy, Inc., of Queens was chartered today with $10,000. capital, to deal in milk, butter, cream and cheese. David C. and Rose Schwartz of Union Course and Bessie Greenbaum of Manhattan are directors.
A similar incorporation notice in another publication listed the Schwartz’s address as 240 Drew Avenue (now 75th Street) in Woodhaven.
In 1920, census records indicate that David C. and Rose lived on a dairy farm located on Juniper Swamp Road in Middle Village Queens and later, in 1930 and 1940 on a farm on Caldwell Avenue, also in Middle Village. Both farms were run by members of the Schwartz family. Based on this I assume that they were bottling and selling/delivering milk for one or both of these farms as early as 1915.
The Schwartz Dairy, Inc. was apparently the predecessor of the Elmhurst Dairy that was started in 1919 by two members of the Schwartz family, Max and Arthur Schwartz. Elmhurst Dairy is listed as early as the 1922 Copartnership and Corporation Directory for Brooklyn and Queens and remained in business through 2016.
The bottle I found is a machine-made quart. It’s heavily sun-purpled indicating the presence of manganese dioxide which was predominantly used as a decolorizing agent prior to 1920.This supports a manufacture date right around the time of incorporation in the 1915-1920 range.
The story of the M H Renken Dairy Co. is told in detail in a June 16, 2015 paper prepared by the Landmarks Preservation Commission proposing landmark status for two Renken Buildings, the dairy office and engine room building. The buildings, located at Myrtle Avenue and Classon Avenue, were part of the dairy complex that encompassed most if not all of the block bounded by Myrtle Avenue, Classon Avenue, Willoughby Avenue and Emerson Place. Much of the information that follows has been summarized from the Landmarks Preservation Commission document. (In much greater detail than I could ever hope to dig up on my own!)
Martin Henry Renken immigrated to the United States in 1872 and in 1888 he founded a dairy on Park Avenue and Spencer Street in Brooklyn. At the start the dairy had only one route that was served by a single horse and wagon driven by Renken. By 1896 the business had moved to 864 Bedford Avenue and was called the Bedford Dairy. Around this time the company established it’s first creamery in upstate New York where milk was received from area farmers and shipped, on a train car refrigerated with ice to Hoboken. In Hoboken it was picked up by wagon, ferried across the Hudson River and taken to the dairy via the Brooklyn Bridge.
By 1903, the business had begun to purchase property on the Myrtle/Classon block and had moved their offices to 204 Classon Avenue. A year later, in 1904, it was listed as the M H Renken Dairy as well as the Bedford Dairy. Around this time, the company had one wholesale route and ten delivery routes. In addition, they had added a distribution center in Borough Park and several more creameries in upstate New York and Pennsylvania.
The business incorporated in 1912 as the M H Renken Dairy Co. By 1914, the company continued to expand and had moved their offices to 131 Emerson Place (the address embossed on one of the bottles I found). Less than ten years later, in a May 16, 1923 advertisement Renken listed seven branches in addition to the Emerson Place plant, five in Brooklyn and two in Queens.
By 1930 they were expanding into Long Island where they opened a new distribution center in Rockville Centre that supported a completely motorized delivery fleet.
At this point Renken was NYC’s largest “independent” dairy, behind national conglomerates Borden and Sheffield Farms.
In 1934, Martin Renken died and was succeeded by his son, Henry as President. At this time, the company was at its peak, operating about 300 delivery routes and employing over 600 people. By this time the business had a subsidiary called United Creameries that I’m guessing encompassed their rural facilities in upstate NY and Pennsylvania. A 1930 advertisement mentioned 12 upstate New York creameries in Orange, Herkimer, Steuben and Tioga counties alone. In 1938, Renken was bottling over seven million quarts of milk a year, all pasteurized and bottled at the Myrtle/Classon complex.
In the 1950’s Renken began to succumb to the trend away from home milk delivery and toward the suburbanization of dairy processing and packaging and by 1959 it shut down milk processing at its main plant. At the time, Renken was still delivering and markrting milk under their name but Sealtest Dairy had taken over the processing. In 1965 Elmhurst Milk and Cream Company took over the processing and local delivery routes, leaving Renken with just wholesale deliveries. Finally, Renken was sold to Beyer Farms in 1986 and the Renken label was discontinued several years later.
I found 2 quart bottles and one half-pint bottle. One of the quart bottles has the 181 Emerson Pl. address embossed on it. The bottles appear to have been made in the late 20’s to mid 30’s based on numbered codes at the base. This dates them in and around the peak period of the business.
