Friedrich Christian Accum or Frederick Accum (29 March 1769[citation needed] – 28 June 1838) was a German chemist, whose most important achievements included advances in the field of gas lighting, efforts to keep processed foods free from dangerous additives, and the promotion of interest in the science of chemistry to the general populace.[1] From 1793 to 1821 Accum lived in London. Following an apprenticeship as an apothecary, he opened his own commercial laboratory enterprise. His business manufactured and sold a variety of chemicals and laboratory equipment. Accum, himself, gave fee-based public lectures in practical chemistry and collaborated with research efforts at numerous other institutes of science.
Intrigued by the work of Frederick Winsor, who had been championing the introduction of gas lighting in London, Accum too, became fascinated by this innovation. At the request of the Gas Light and Coke Company, he carried out many experiments in this novel field of inquiry. After a time of close working association with this company, he became a member of its board of directors in 1812. The company was charged with founding the first gasworks in London to supply gas lighting to both private and public areas. Accum was instrumental in the conception and design of this extremely successful gasworks.
The majority of Accum's publications were written in English. They were executed in a style that made them quite accessible. Many scientific contributions were brought forth through his writings, which were influential in the popularization of chemistry during this era. In 1820, Accum published A Treatise on Adulterations of Food and Culinary Poisons, in which he denounced the use of chemical additives to food. This work marked the beginning of an awareness of need for food safety oversight. Accum was the first person to tackle the subject and to reach a wide audience through his activities. His book, controversial at the time, found a wide audience and sold well. However, it threatened established practices within the food processing industry, earning him many enemies among the London food manufacturers. Accum left England after a lawsuit was brought against him. He lived out the rest of his life as a teacher at an industrial institution in Berlin.
Life and work
Youth and education
Accum was born in Bückeburg,
At the time of his conversion baptism, the senior Accum changed his name from Markus Herz to Christian Accum. In addition to choosing the name "Christian," Accum's father chose to emphasize his newly embraced religion by adopting the surname Accum, which derives from the Hebrew word "Akum," meaning "not-Jewish." It is not known whether he did this on his own initiative or because of pressure from his fiancee's family. After his marriage, Christian Accum opened his own soap-making shop in Bückeburg at his in-law's home. Nine years after his marriage to Judith, he received legal citizenship from the city.[3]

In 1800, Accum and his family changed residence in London from 17 Haymarket to 11 Old Compton Street. There he would live for the next twenty years. His family home also served as a school, an experimental laboratory and place he sold chemicals and scientific instruments. Accum's business cards of the time described his activities thus:
Mr Accum acquaints the Patrons and Amateurs of Chemistry that he continues to give private Courses of Lectures on Operative and Philosophical Chemistry, Practical Pharmacy and the Art of Analysis, as well as to take Resident Pupils in his House, and that he keeps constantly on sale in as pure a state as possible, all the Re-Agents and Articles of Research made use of in Experimental Chemistry, together with a complete Collection of Chemical Apparatus and Instruments calculated to Suit the conveniences of Different Purchasers.[9]
For many years, Accum's establishment was the only significant institution in England that provided lectures on the theory of chemistry as well as training in laboratory practice. Amateurs were welcome to perform simple experiments on site to enhance their knowledge. Accum's teachings attracted various prominent students. These included the well-known London politician and later prime minister
With the development of new laboratory apparatus, Accum positioned himself in the middle market range with respect to cost and usability. Accum developed portable laboratory kits, intended for farmers, for the analysis of soils and stones. With affordable prices ranging from three to eighty
Teacher and researcher
In March 1801, Frederick Accum was offered a position at the
By 1803, Accum had published a series of articles in
Accum held his first lecture on chemistry and mineralogy in a small room in his house on Old Compton Street. His audience grew so rapidly that he soon had to rent the Medical Theatre on Cork Street. After resigning from the Royal Institution and taking a new position with the Surrey Institution, he continued with his popular lectures. An advertisement in The Times on 6 January 1809 indicates that Accum offered a course on mineralogy and the chemical analysis of metals every Wednesday evening.[16]
His increasing interest in mineralogy at this time is also apparent from the titles of two books he authored between 1803 and 1809. The first was a two volume work that appeared in 1804 entitled A Practical Essay on the Analysis of Minerals, which was reissued in 1808 as A Manual of Analytical Mineralogy. In 1809 he published Analysis of a Course of Lectures on Mineralogy. Beginning in 1808, while at the Surrey Institution, Accum also published, a series of articles on the chemical properties and composition of mineral water in Alexander Tilloch's Philosophical Journal.[17]
In 1811, when the Parisian
Accum's role in the history of gaslight
Artificial lighting of any sort was largely absent during the industrial development of the late 18th and early 19th centuries. Using candles or oil lamps to illuminate a textile factory was costly, and economically unsound. With the advent of industrial means of production, not only were new textile halls physically larger, but they also had to be lit more brightly for longer periods of time. Driven by great demand, and made possible through Lavoisier's theoretical work regarding the role of oxygen in combustion, the end of the 18th century saw a continuous series of improvements in lighting technology.[19]
The production of gases from coal had been noted by Henry Clayton. He shared this observation with Robert Boyle in a letter written in the 17th century. The letter was published in the Philosophical Transactions of the Royal Society in 1739. Clayton wrote:
I then got some Coal from one of the Pits nearest thereunto, which I distilled in a Retort in an open Fire. At first there came over only Phlegm, afterwards a black Oil, and then likewise a Spirit arose, which I could noways condense, but it forced my Lute, or broke my Glasses. Once, when it had forced the Lute, coming close thereto, in order to try to repair it, I observed that the Spirit which issued out caught Fire at the Flame of the Candle, and continued burning with Violence as it issued out, in a Stream, which I blew out, and lighted again, alternately, for several times.[20]
Clayton's findings did not have any practical application until the end of the 18th century. The gas produced during the
Accum became involved with the production of gas for lighting purposes through the efforts of
In London, in 1814, there was a single gasometer of 400 m3 (14,000 cu ft), by 1822, there were four gas companies, whose gasometers had a total combined volume of almost a million ft3[25] To keep delivery routes for the gas pipelines as short as possible, gas plants were set up within the city districts where the gas was consumed. The arrival of these types of chemical plants to inhabited parts of the city provoked public criticism of the new technology. This was also directed at poisonous effluent generated by the plant operations. These harsh critiques were especially fierce once accidental explosions occurred at some plants.[26] Accum, who by this point was a leading proponent of gaslight in addition to his work as a chemist, strongly refuted these criticisms in his writings. Through careful analysis he showed that as a whole, accidents were caused by carelessness of plant workers rather than problems with the technology, and were therefore avoidable.[27]
From early on in its conception, Accum had been concerned with the byproducts of coal gas production, which included tar and sulphur compounds. These were typically buried or dumped into nearby waterways. The ammonium and sulphur compounds were especially damaging to the environment. In 1820, Accum began demanding legal measures to prevent the discharge of these byproducts into the sewage systems and rivers.[28]
"There is death in the pot"
In 1820 Accum began the public struggle against harmful food additives with his book entitled A Treatise on Adulterations of Food and Culinary Poisons. Some additives derived from plants, and used as preservatives or to alter tastes or appearance, had already been in use for some time. The beginning of the 19th century saw a rapid increase in the industrial preparation and packaging of foods. The drastic increase of additives used in these processes became a serious health concern. The production and distribution of food, instead of being one between local farmers and townspeople, increasingly became a centralized process in large factories. The proliferation of newly discovered chemicals and the absence of laws moderating their use, made it possible for unscrupulous merchants to use them to boost profits at a cost to the public health.[29] Accum was the first to publicly proclaim the hazards of this practice and to reach a wide audience with his concerns.[30]
Accum alludes to his moral stance on food adulterations as he claims that:
The man who robs a fellow subject of a few shillings on the high-way, is sentenced to death; while he who distributes a slow poison to a whole community, escapes punishment.[31]
A thousand copies of A Treatise on Adulterations of Food and Culinary Poisons were sold within a month of its publication.[32]
The various chapters of the book alternate between harmless forgeries such as mixing dried pea grounds in coffee, and much more dangerous contamination by truly poisonous substances. Accum explained to his readers that there was a high
Accum paid particular attention to beer, introducing the subject with the comment: "Malt beverages, and especially port, the preferred drink of the inhabitants of London and other large cities, is among the items which is most frequently adulterated in the course of supply."[36] He claimed that English beer was occasionally mixed with molasses, honey, vitriol, pepper and even opium. Among the most shocking customs he pointed out was the practice of adding fishberries, part of the family Menispermaceae, to port. It became evident during the French Revolutionary Wars that the practice was getting out of hand, and Accum attributed the intoxicating power of the drink to the addition of this plant matter.[37]
The Treatise on Adulterations of Food and Culinary Poisons has two further notable characteristics. First, like Accum's earlier writings, it was written with descriptions of the simple techniques of analytical chemistry he employed, thereby making them more accessible to his readers. He wanted to make every test repeatable in the simplest possible way by a non-expert. Accum wrote in the foreword to his first edition:
In stating the experimental proceedings necessary for the detection of the frauds which it has been my object to expose, I have confined myself to the task of pointing out such operations only as may be performed by persons unacquainted with chemical science; and it has been my purpose to express all necessary rules and instructions in the plainest language, divested of those recondite terms of science, which would be out of place in a work intended for general perusal.[38]
The second characteristic was that Accum did not limit his campaign to simply exposing problems. At the end of every chapter, he included names of merchants of who had in years prior to 1820 been caught adulterating foodstuffs. In this way, Accum tried to deprive them of business and thereby had an effect on the London economy.[39]
Reaction to Treatise on Adulterations of Food
Accum was well aware before the publication of his book that mentioning specific names from London's business world would provoke a resistance and a possibly a severe reaction. In the foreword to the first edition he called the publication of the names of those adulterating foodstuffs an "invidious office" and a "painful duty,"[40] which he undertook as a verification for his statements. Although he further stated that he carefully avoided citing any except those authenticated in Parliamentary documents and other records,[41] this did not save him from the ire of his opponents. By the time the second edition appeared, he mentioned in the foreword that he had received threats. At the same time, this did not stop him from putting "the unwary on their guard" against the deceits of unscrupulous men. He further added that he wished to notify his hidden enemies that he would report for posterity the crimes these swindlers and their base associates had been found guilty of in public justice—that is, of having made basic foodstuffs poisonous.[42]
Scandal and lawsuit
The process that ultimately led to Accum's departure from England and return to Germany began a few months after the publication of his book on the poisoning of foodstuffs. For a long time, many contradictory accounts have been given of the exact circumstances of his exile. Finally in 1951, R. J. Cole, in an addendum to the minutes of Royal Institution, proved that the presentation of the events adopted in the article in the Dictionary of National Biography,[43] and also later in the Allgemeinen Deutschen Biographie.[44]
Cole completely reprinted the minutes of an extraordinary meeting of the Royal Institution of 23 December 1820,[45] which show that these events were initiated through an observation made by a librarian of the Royal Institution named Sturt. Sturt reported to his superiors that on 5 November 1820, a number of pages were removed from books in the reading room of the institution, books Accum had read. On the instructions of his superiors, Sturt cut a small hole in the wall of the reading room to watch Accum from an adjoining room. On the evening of 20 December, as recorded in the minutes, Sturt could see Accum tear out and walk off with a paper concerning the ingredients and uses of chocolate. The paper had been in an issue of Nicholson’s Journal. Accum's premises on Old Compton Street were searched on the order of a magistrate for the City of London, and torn pages were indeed discovered there. These could be matched to books belonging to the Royal Institution.
The Magistrate after hearing the whole of the Case observed that however valuable the books might be from which the leaves found in Mr Accum’s house had been taken, yet the leaves separated from them were only waste paper. If they had weighed a pound he would have committed him for the value of a pound of waste paper, but this not being the case he discharged him.[46]
The Royal Institution committee that met on 23 December 1820 was not, however, satisfied with this judgment, and decided to take further legal action against Accum. On 10 January 1821, an open letter directed to
Return to Germany
In the two years before his return to Germany, Accum had published a number of books dealing with nutrition chemistry. In 1820, he published two works, one on beer production (A Treatise on the Art of Brewing) and another on wine (A Treatise on the Art of Making Wine). The following year appeared Culinary Chemistry, in which Accum provided practical information about the scientific basis of cooking. He also published a book on bread (A Treatise on the Art of Making Good and Wholesome Bread). Even when he had returned to Germany, his works continued to be reprinted and were translated into French, Italian and German, reaching a wide readership in Europe, as well as in the US after it was reprinted there.[51]
Immediately upon his arrival in Germany, Accum went to the town of Althaldensleben. There, the industrialist Johann Gottlob Nathusius had acquired various estates and was using them to found a sprawling industrial settlement. Nathusius was a German pioneer in the field of sugar production from beets, and had established a factory for its production in that town between 1813 and 1816. It was probably Nathusius’ extensive library and chemical laboratory that drew Accum. He remained only a short time in Althaldensleben, however, as he soon got a professorship at the Gewerbeinstitut and the Bauakademie in Berlin. His teaching in the areas of physics, chemistry, and mineralogy, were collected in the two volume work, Physische und chemische Beschaffenheit der Baumaterialien, deren Wahl, Verhalten und zweckmässige Anwendung, published in Berlin in 1826. It was the only work Accum published originally in German.[52]
A few years after settling down in Berlin, Accum had a house built at 16 Marienstraße (later 21 Marienstraße), where he dwelt until his death. During his last years, he suffered from a bad case of
