In the 18th century and earlier, most baking was dictated by the delicate whims of respiring yeast. But how many know their connection to an everyday kitchen product, baking powder? Rumford Baking Powder was manufactured at the Rumford Center from 1869 to 1968. In early America, making a cake was an ordeal. Technical Divisions Within a few months of arriving in Concord, Thompson married the Reverend's daughter, Sarah Walker Rolfe, whose deceased first husband left her a large estate. It was not a happy marriage; the couple separated in 1809, and Rumford moved to Auteuil, where he died in 1814. In 1861 the boundary between Massachusetts and Rhode Island was adjusted with the result that East Seekonk Massachusetts, became part of East Providence, Rhode Island, so the corporation had to be chartered again in Rhode Island. Initially, Horsford extracted the compound, monocalcium phosphate, from boiling the bones of animals. No doubt this close connection eased Horsford's stay in Germany since Giessen was a small town of only about 8,000 people and the University of Giessen had only about 500 students, of whom sixty were studying chemistry. Horsford entered the Rensselaer School (now Rensselaer Polytechnic Institute) in 1837, graduating a year later with a B.S. The mixing of sodium bicarbonate and cream of tartar marked the introduction of baking powder.

Bread is considered a basic foodstuff; eaten down through the ages, it continues to be a staple of the modern diet. Antonio and Sylvie Roder, (New York: Abrams, 1999) and the following Web sites: "The Story Behind a Loaf of Bread: The History of Bread. As a thirteen-year-old, Thompson was apprenticed to a Salem merchant for three years. This was packaged in bottles, but Horsford was interested in using metal cans for packing; this meant the mixture had to be more moisture resistant. After that, he served as an apprentice clerk in Boston, enrolled as a medical student, and taught school. I was interested by it since I get regular requests for low-sodium recipes, and the good folks at Clabber Girl were happy to send along a sample for me to try. Engraving published in 1886 Manufactory of Rumford baking powder, ca.1910 Rumford Chemical Works was founded by Eben Horsford, who was the Rumford Professor and Lecturer on the Application of Science to the Useful Arts at Harvard University, and entrepreneur George F. Wilson. Baking powder was the main output of the Rumford Chemical Works. By the mid-1860s “Horsford’s Yeast Powder” was on the market as a pre-mixed leavening agent. Rumford Chemical Works. In that same collection are remnants of the ugly wars fought within the growing baking powder industry around the turn of the 20th century. The development of baking powder made baking easier, quicker and more reliable for bakers in the mid-19th century. The Collegium Pistorum did not allow bakers or their children to withdraw from the guild and enter other professions; but it did protect the special privileges the state granted bakers. But there's more to baking powder than fluffy biscuits, and some simple acid-base chemistry is the key. Even when it did work, leavening was a tedious process. Now established as a professor, Horsford married Mary Gardiner on August 4, 1847. Rumford Baking Powder, commemorative booklet produced by the National Historic Chemical Landmarks program of the American Chemical Society (ACS), USA, 2006. Keep up-to-date on: © 2020 Smithsonian Magazine. Geologists were aware of U.S. phosphate deposits, but they were not exploited until 1869. In the early years of the factory the source for calcium was bones, which were treated with sulfuric acid. Over six years of fighting, millions of dollars in bribes were paid, dozens were sent to jail for simply selling baking powder, and the muckraking press forced the resignation of the state's lieutenant governor. Rumford Chemical Works was founded by Eben Horsford, who was the Rumford Professor and Lecturer on the Application of Science to the Useful Arts at Harvard, and George F. Wilson in 1854 in Seekonk, Massachusetts part of which in 1862 became East Providence, Rhode Island.The Rumford Chemical Works was incorporated in Massachusetts in 1859. the Baking Powder War. Jan 9, 2014 - Count Rumford: invented Rumford fireplace design and Rumford Baking Powder This was accomplished by the addition of corn starch, and in 1869 Rumford began the manufacture of what can truly considered baking powder. Some of these cookbooks are held today in the collections of the Smithsonian’s National Museum of American History. PLUS, Rumford’s packaged it in the convenient red can, so all you had to do was spoon it out. That was the rhetorical question posed in 1891 by Eben Norton Horsford, a chemistry professor at Harvard and developer of Rumford Baking Powder. By 1899 Clabber brand baking powder had been introduced, and today the Clabber Girl brand, as renamed in 1923, is distributed nationwide and to many different countries around the world. Stop Ruining Your Christmas Cookies! Rumford played a major role in the early success of the Institution, which was founded at a time when there were no institutional laboratories, and scientists conducted experiments in their homes. “Baking powder is a crystalline powder that combines baking soda with dry acidic ingredients that react when water is added, plus cornstarch to prevent clumping and to control the amount of gas produced per unit of baking powder” (Joachim & Schloss, 2008). (Many early recipes recommend obtaining the help of a manservant.). Eben Horsford’s unique formula was an important innovation and made the making of biscuits, cookies and other quick baking products simpler than before. Cream of tartar greatly improved and regularized the baking process since the uniformity of both sodium bicarbonate and cream of tartar offered bakers better control of the leavening process, allowing for predictable results. He started selling his product under the name “Rumford Baking Powder”. It was not uncommon for young Americans to travel to Europe in the 19th century for advanced scientific training, especially at German universities. His inventions include a photometer and a calorimeter, and, given his interest in the "useful arts," he devised a stove, a roaster, and a lamp with multiple wicks. In advertisements, Royal touted the "purity" of its more expensive product, while claiming that other baking powders were "injurious" to one’s health. Throughout his career, Horsford continued to experiment extensively with possible techniques and preparations for baking powder. An advertisement for Rumford baking powder can be found on the first page with the last page containing an illustration of the various medals the baking powder has won including the 1876 Centennial Exposition and the 1893 World's Columbian Exposition. He cleaned the streets of Munich of beggars, giving them clean quarters and putting them to work. This may be said to be the first truly modern bread. In this early form of baking powder, the MCP and soda were wrapped individually, later being blended with cornstarch to be sold as Rumford Baking Powder. History Lives Here. "The flour should be dried before the fire, sifted and weighed; currants washed and dried; raisins stoned; sugar pounded, and rolled fine and sifted; and all spices, after being well dried at the fire, pounded and sifted," reads a common cake recipe in the 1841 cookbook Early American Cookery. Published by Rumford Chemical Works, this almanac features advertisements for Professor Horsford's baking powder and acid phosphate along with other products manufactured by Rumford … Through much of history the color of bread revealed social status: the darker the bread, the lower a person's status. As a result, most bread makers continued to use sour dough.3. Eben Norton Horsford, The Theory and Art of Bread-Making: A New Process Without the Use of Ferment (Cambridge, Mass: Welsh Bigelow & Co., 1861). That was the rhetorical question posed in 1891 by Eben Norton Horsford, a chemistry professor at Harvard and developer of Rumford Baking Powder. Besides this grueling work, you had to plan ahead. "("Stradley(a)", n.d, para.5). The acid component, calcium acid phosphate, originally manufactured from bones, replaced cream of tartar, an expensive byproduct of the European wine industry. Learn about financial support for future and current high school chemistry teachers. Learn More. Wow. Bakers began buying both chemicals in bulk, but they had to be kept separate to prevent a premature acid-base reaction occurring. Other competitors soon sprung up, and Royal was willing to resort to vicious tactics to gain control of the market. Dr. Oetker. A new cranberry recipe made with Rumford all-phosphate baking powder is offered here. It appears that Thompson envisioned a brighter future outside England since the influence of his friends and patrons had waned. For more than three millennia, the method of baking bread did not change substantially; that is, until the 1830s when bakers began adding sodium bicarbonate (bicarbonate of soda) and sour milk to their dough. The professorship was created in 1816 and the third Rumford Professor was Eben Horsford. In late 1775 Thompson sent General Howe, Gage's successor, a lengthy report on the numbers, disposition, and equipment of American forces surrounding Boston. And there was an additional problem as cream of tartar was imported from France and Italy. Grown in ancient Mesopotamia and Egypt, wheat was probably chewed at first. In the presence of moisture carbon dioxide is released, leavening biscuits, cookies, or other quick baking products. At its height of activity around the turn of the century, Rumford Chemical included 300 acres of working farms and communities to sustain the factory workers, and the Village of Rumford was called the "kitchen capital of the world." This process was unpredictable, since it was hard to control how acidic the sour milk actually was, meaning it was difficult to know how much baking soda to use or how long to bake for. Now, instead of purchasing two separate ingredients at the pharmacy (where chemicals were sold at the time), and having to precisely measure out each one, would-be bakers could grab one container off the grocery store shelf and be ready to go. Use of Baking Powder Makes Less Sugar Necessary In Preparation of Sauce. In 1780 Thompson became Secretary of State for the Northern Department, which comprised New York, New England, and sections of Canada. This was accomplished by 1911 softcover booklet of recipes Very good condition, minor blemishes of age, no writing or markings. The cultivation of wheat predates recorded history.

In the 1860s, a lot of companies added other ingredients in their baking powders. In addition to marketing Horsford's pulverulent phosphoric acid, the firm was producing hydrochloric and nitric acids and tin chloride. Today's blog post comes to you from our guest author, CHC volunteer Michael Kenney. Horsford went on to start Rumford Baking Powder, but a few years later, he faced competition from newcomer Royal Baking Powder. This group had an international flavor, due entirely to the presence of Liebig on the faculty. . See the container for the best by date. There have been many carbonate and acid mixtures made to sell as baking powders (Romanowski, 2006). The next time you pull out that mason jar of baking powder from the cupboard, think of the history behind such an unassuming ingredient. American Chemical Society National Historic Chemical Landmarks. What also made Rumford special was its use of calcium phosphate in … This discussion is informed by the following: Bernard Dupaigne, The History of Bread, trans. This process extracted monocalcium phosphate, creating an acid that would react with baking soda to create CO2. No doubt, Rumford's interest in public facilities for scientific research stemmed from his own scientific inquiries. This appointment apparently caused resentment among his neighbors who felt there were veterans of the French and Indian War better qualified for the commission. He mixed the two in a container with a little cornstarch and baking powder was born. Collaborate with scientists in your field of chemistry and stay current in your area of specialization. But preferences change; today, darker breads are more expensive and prized for their taste and nutritional value. Professor Eben Horsford and George Wilson joined forces to establish a plant to manufacture chemicals needed by New England's many and varied industries. Rumford Chemical Works then began the manufacture of what can be considered a true baking powder. It became part of Rhode Island in 1862. This academic post had been established by Count Rumford, an inventor and entrepreneur. Without this miraculous white substance, "We literally would not have cake as we know it now," says Linda Civitello, a food historian and author of the new book Baking Powder Wars. History of Baking Powder: 1843 – The first modern version of baking powder was discovered and manufactured by Alfred Bird (1811-1878), British chemist and founder of Bird and Sons Ltd. His improved version of baking powder was created so he could make yeast-free bread for his wife, Elizabeth, who had allergies to eggs and yeast. Rumford Chemical Works, where baking powder was made, was designated a National Historic Chemical Landmark in a special ceremony on June 12 in East Providence. In 1859, US chemist Eben Horsford launched Prof Horsfords Self Raising Bread Preparation, using powdered monocalcium phosphate (MCP), which he had patented in 1856. In fact, you can still find artifacts of our industrial roots around the campus! In a phrase, baking powder. Baking powder was an incredible invention in 1859 – it gave the needed leavening power to batters and dough but prior to Rumford, the leavening power varied greatly in degree depending on what baking powder the cook used. He also occasionally attended lectures at Harvard University on physical science.14 In 1772, when he was nineteen, Thompson was summoned by the Reverend Timothy Walker to teach in Concord, New Hampshire, which earlier had been known as Rumford.15. 17th Annual Photo Contest Finalists Announced. Rumford Baking Powder National Register of Historic Places [ edit ] The surviving parcel, roughly 8.5 acres (3.4 ha), includes a few wood-frame buildings which may date to the 1857 move and a large three-story brick warehouse built in 1895. Horsford spent two years in Giessen, studying the nutritive value—including the protein content—of various grains among other topics in organic chemistry. Throughout the Middle Ages and well into the modern era the price and availability of bread was often linked to social stability. This required extra time in measuring. Horsford worked at a time when chemistry was only just beginning to be considered a respected field, and ended up creating the first modern chemistry lab in the United States at Harvard University.
