Rockwood & Company

Rockwood & Company is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Rockwood & Company rather than just read about it. In short: Rockwood & Company was a New York City-based chocolatier which operated from 1886 until 1957. It coordinated the industry's first resale price contracts, operated the largest chocolate factory in New York, and was the second largest producer of chocolate in the United States, after the Hershey Company.

Key takeaways

  • Rockwood & Company belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Rockwood & Company to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Rockwood & Company from memory before moving on to harder problems.

Reference excerpt

Rockwood & Company was a New York City-based chocolatier which operated from 1886 until 1957. It coordinated the industry's first resale price contracts, operated the largest chocolate factory in New York, and was the second largest producer of chocolate in the United States, after the Hershey Company. Founded in the borough of Manhattan, it moved to the Brooklyn neighborhood of Wallabout, gradually expanding its footprint to occupy most of a city block. In 1919, a fire led to a flood of chocolate in the street, attracting a crowd of children. Rockwood & Company sold the factory to the Sweets Company of America in 1957, who used it to produce Tootsie Rolls until it closed in 1967. The Rockwood & Company factory complex was listed on the National Register of Historic Places in 1983, which was later merged into the Wallabout Industrial Historic District. It was converted to luxury apartments in 1996.

Business history Wallace T. Jones and W. E. Rockwood founded Rockwood & Company in 1886 and originally operated a chocolate factory on Cherry Street in Manhattan until 1904, when it moved to Brooklyn. At the time, it was the second largest producer of chocolate in the country, next to Hershey's. It processed raw cocoa into chocolate and made coatings, bars, cocoa, baking chocolate, and other confections. Rockwood may have been the first to introduce chocolate sprinkles (marketed as "Decorettes") to the United States circa 1915, and in the mid-1950s its bestselling product was chocolate chips (marketed as "Chocolate Bits"). The company's treasurer, William M. Evans, was elected president in 1923 and moved to the role of chairman of the board in 1933 until his death in 1944. Jones' son, Wallace Thaxter Jones, became president in 1933. The factory's 1,000 workers went on strike for eleven days in August 1937, after a Pennsylvania chocolate workers' strike earlier that year. A few months later, Rockwood was part of the industry's first resale price contracts when it ensured its product, Pecan Feast, would be sold for a minimum of 5 cents. When the younger Jones died in 1946, H. Russell Burbank was promoted from executive vice president to president of Rockwood & Co. Among its marketing activities Rockwood awarded $1,000 scholarships to winners of the Pillsbury bake-off if they used Rockwood products. This tactic bore fruit when an entry for "Starlight Mint Surprise Cookies" won the $10,000 second prize at the 1949 contest, and the recipe was included in packages of both Pillsbury and Rockwood products. The New York Times reported on a string of cocoa bean thefts at the factory in 1954, and how the police followed a truck driver who was selling part of his cargo. Two hundred thousand dollars of cocoa beans were estimated to have been stolen, at the then-price of 54¢ a pound, dropped off at a Gowanus Canal warehouse while being transported to the Erie Basin. The company was affected by a global shortage and rise in the price of cocoa beans that year to more than 50¢ a pound. Spending more on beans, but unable to change the retail price, the company started losing money. As they looked to sell the company, Jay Pritzker purchased a controlling interest of Rockwood stock, stopping the production of cocoa butter in order to sell cocoa beans themselves through a loophole which would avoid paying tax on the sale. He traded the beans to shareholders for more of the company's stock. His pricing ensured shareholders would want to sell, and presented an opportunity for arbitrage that Graham-Newman took advantage of, buying shares and immediately trading them to Pritzker for more valuable beans. A young Warren Buffett, who worked at Graham-Newman, bought shares but did not participate in arbitrage, understanding from Pritzker's point of view that, in the end, the more profitable company would be worth more. The stock price more than quintupled in the end. There was another strike in 1957, when the workers, who were members of the Bakery and Confectionary Workers International Union, stopped work amid concerns over severance payments in case the company went out of business. The following month, April 1957, the Rockwood Chocolate division was sold to the Sweets Company of America (now Tootsie Roll Industries). As part of the deal, the union sacrificed half of their vacation pay.

Brooklyn factory complex The original Brooklyn building is on the corner of Park Avenue and Washington Avenue, in the Wallabout neighborhood, which was a major industrial center at the time. It was initially constructed in 1890 for the Van Glahn Brothers grocer. Rockwood began leasing the space in 1904, having outgrown its Manhattan factory, and expanded gradually through the 1910s. It acquired the rest of the Van Glahn properties and erected new buildings, first northwards towards Flushing Avenue and then west towards Waverly Ave. Among the new construction was a new factory on the northwest part of the block, on the corner of Waverly and Park. Parfitt Brothers designed it, with a showroom on the first floor designed by Ernest Flagg. According to the Brooklyn Daily Eagle in 1910, it was the largest chocolate factory in the state and one of the largest in the country. It increased the total factory floor space to more than 125,000 square feet. After the factory was sold to Sweets Company of America in 1957, it produced Tootsie Rolls and operated for ten more years, before closing in 1967. In 1983, it was listed on the National Register of Historic Places as the Rockwood Chocolate Factory Historic District, but remained vacant until 1996, when a developer purchased it and converted it into luxury apartments. The factory complex, and the rest of the historic district, was incorporated into the larger Wallabout Industrial Historic District in 2012.

Worked examples

Example 1 — a first encounter with Rockwood & Company

Start with the simplest possible case. Write down what Rockwood & Company claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Rockwood & Company before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Rockwood & Company ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Rockwood & Company

In research
Rockwood & Company appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Rockwood & Company in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Rockwood & Company is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1886 establishments in New York (state), 1957 disestablishments in New York (state), Chocolate companies, so understanding it makes those chapters shorter.
In everyday life
Look for Rockwood & Company outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
