L’Hoir Comes to the Aid of the Sugarmakers

By Pierre Prévost

 Au fil des ans, Revue de la Société historique de Bellechasse (Winter 2018) Vol. 30, No. 1, pp. 23-28.

On April 10, 1936, American customs officers blocked three wagons of maple products shipped by the Quebec maple sugar Cooperative. Lead contamination is involved, the heavy and toxic metal that causes dreaded effects on the nervous system. Research performed in Vermont a few months earlier indicated the presence of lead in sap collected from maple trees. Since this observation, federal inspectors are vigilant and strict.

 

Americans want quality

Since 1906, the Pure Food and Drug Act prohibited the sale of contaminated food on American soil. Americans had been burned in the 1920s by Canadian maple sugar that was often of poor quality and in which was sometimes found oat bran, brown sugar, and even pebbles. The minister of Agriculture of the time, Joseph Edouard Caron, then appointed Cyrille Vaillancourt to organize Quebec maple syrup producers and promote the production of quality sugar and syrup. On May 2, 1925, the “Cooperative of Quebec maple sugar producers” was born and a campaign to educate the maple industry was in full swing. In the fall of 1928, Plessisville located at the center of the maple syrup region, became home to the packaging and processing factory. Vaillancourt brought the maple industry to a level never before seen, and in the 1930s even managed to break the monopoly on purchasing Quebec syrup held by American George Cary. This time the problem is quite different and Vaillancourt must remedy it.

The chemists of the Plessisville laboratories do not give up. They find the presence of lead in the shipped syrup and, powerless, appeal to their colleagues from all walks of life. They get the support of Elphège Bois, director of the Department of Biochemistry at Laval University, who, after some experiments, manages to solidify the lead and extract it from the unsaleable syrup. The seized cargo is subjected to the treatment and the purified syrup is allowed to proceed Chicago.

However, the problem of contamination with lead oxides is found to occur in the early stages of maple syrup production, a bitter conclusion of the chemists from Plessisville. Lead is likely entering syrup from the collection and storage of sap. Spiles, sap pails, evaporation equipment, transport containers and tanks are targeted, because tinned iron and solder release a tiny amount of heavy metal when in contact with maple sap and syrup, which are acidic in nature, with a pH between 3.4 to 6.6. Aluminum would be the ideal replacement material but is too expensive for maple syrup producers. The main concern of Cyrille Vaillancourt, the manager of the maple sugar cooperative is to find a manufacturer capable of producing good quality aluminum buckets with a two-gallon capacity.

In a random conversation, Cyrille Vaillancourt hears about the director of a specialized stainless-steel factory located in Liège, Belgium. There was a big report in the news a few years earlier about Professor Auguste Picard who was the first researcher to access the remotest part of Earth’s atmosphere. In the meantime, with a restructuring of the Food and Drug Administration in 1938, Washington was tightening its control of food in the United States.

 

The expertise of L’Hoir

Originally from Switzerland, Auguste Piccard (1884-1962) became an expert in physics and went to university in Brussels to teach. In 1929, Piccard submitted a daring project to the national scientific research fund recently founded by King Albert. Seduced by the idea of exploring the stratosphere in a balloon, the organization granted him the 400,000 Belgian francs required for the experimental manned flight in the upper atmosphere. Piccard needed a lightweight sphere made from a sufficiently robust aluminum that could withstand an environment where the pressure is only a tenth of that measured on the ground.

Piccard went to meet Georges L’Hoir, who then ran a beer can manufacturing factory in Angleur, on the outskirts of Liège, the cradle of the zinc industry and a former world capital of the steel industry. L’Hoir saw no problem with the request despite not knowing what the 2.1 meters in diameter and 3.5 millimeters thick sphere was intended for. This sphere will become the pride of L’Hoir and will help spread their notoriety throughout the world. “This is the first time that we’ve make a beer barrel in this shape! “(Reply by Georges-Armand L’Hoir to Auguste Piccard)

A first test set for September 14, 1930 was postponed due to adverse weather conditions. Early on the morning of May 27, 1931, near Augsburg, Germany, Auguste Piccard, assisted by engineer Paul Kipfer, took off inside the aluminum capsule supported by a balloon that had to expand to a diameter of 30 meters.

Ascending at the rate of half a kilometer a minute allowed him to realize the first pressurized flight while climbing to 15,781 meters, a height never previously reached by a living being and the first of a series of world records assigned to Piccard. Despite some pitfalls, the crew travelled 1,800 kilometers and finally landing on a glacier in Austria, before the reserves of oxygen ran out. Their return to civilization was triumphant and the news toured the globe.

Auguste Piccard returned to Georges L’Hoir’s factory to have a second, improved version of the capsule manufactured: the first having been battered by the squalls of wind during its second test, its tightness was no longer insured. On August 18, 1932, Piccard rose again into the stratosphere, this time with the Belgian engineer Max Cosyns. They reached 16,940 meters altitude.

The exploits of Professor Piccard caused a sensation on all continents and the notoriety of Georges L’Hoir followed in their wake. Cyrille Vaillancourt had found the man for the job to supply millions of revolutionary sap pails. He communicates with the Belgian manufacturer to let him know what he is seeking and sends him samples. A few weeks pass, other samples come back with a written proposal then they wait. To their surprise, in May, Georges-Armand L’Hoir arrives in Lévis, a few days before the royal couple, and knocks on Cyril’s Vaillancourt’s door. It is not L’Hoir’s first visit to American soil, since he monitored the production of buses intended for Belgian government during the Great War. On this trip he wanted to come back to America to establish a new factory. It is said that he was courted by the citizens of Kitchener, Ontario who were ready to build him a factory to accommodate his machinery. The ball was now in the camp of the people of Lévis, and Vaillancourt, administrator of the Caisse populaire de Lévis, worked out some scenarios.

Note: Lévis is a city in eastern Quebec, Canada, located on the south shore of the St. Lawrence River, opposite Quebec City. A caisse populaire in Quebec is most similar to a what is called a credit union in the United States.

With the support of his counterpart Valmore de Billy, president of the Caisse de Lévis, Cyrille Vaillancourt submits a proposal to his colleagues to build a factory for the production of aluminum sap pails in Lévis. The credit committee deliberates and considers two financing scenarios for this project: either a group of citizens endorses Georges-Armand L’Hoir for a loan of up to $ 20,000; or the Caisse builds the factory at its own expense and L’Hoir would rent the facility at cost plus 5% interest. The leaders of the Caisse choose the second option considering that L’Hoir is a recognized industrialist, who has a strong credit rating with banks in Belgium and France, and on the condition that he agrees to stay in Lévis if he wants to expand his factory. A disbursement up to up to $ 20,000 is allowed for the construction of a factory of about 180 feet by 40 situated on reclaimed land by the river, a little downstream from Hadlow Cove. L’Hoir will have to pay monthly rent while the Maple Syrup Cooperative guarantees the purchase of all the sap pails as long as their price and quality are maintained.

The idea of living in a traditional Quebec house that was the birthplace of the poet Louis Frechette quickly seduced the Belgian industrialist. A factory built behind the attractive house would benefit from a dock and access to the Canadian National Railway. Georges-Armand L’Hoir probably made the best choice since a highly militarized Nazi Germany was threating Liège which is only a few away kilometers from the border with Germany.

The Lévis plant is ready to open in the fall of 1939, when the German troops invade Poland, an act which leads to the declaration of war. The metallurgist and his family in retreat from Europe, settled in to their new Quebec home, while the factory receives machining tools and await the arrival of aluminum.

 

A vast replacement operation

Everything is in place to produce sap pails intended for Quebec maple syrup producers. However, aluminum is scarce since the aeronautical industry requires huge amounts of the white metal for the war effort. This situation goes against the views of Adélard Godbout, the newly elected Liberal Minister who was recently elected in solidarity with Ottawa Liberals who supported the war effort but did not advocate for conscription.

An agronomist by training, Adélard Godbout campaigns for the promotion of trade between Quebec and the United States. To this end, he negotiates with the federal government and the Aluminum Company of Canada (ALCAN) to allow a meager but sufficient share of the aluminum for the L’Hoir plant to meet the demands for new sap pails. Using his influence in Ottawa, the prime minister facilitates a temporary supply which, without it, the L’Hoir factory would have to close its doors. Production at the factory is vital for soldiers since it manufactures military containers, among other things. Almost two years have passed since the American embargo on Canadian maple products when, in 1940, Godbout established a trade delegation from the provincial general assembly to New York to promote and highlight Quebec products.

The country waits in vain for the end of rationing on metals. In the September 1940 edition of the publication L’Abeille et l’erable, Cyrille Vaillancourt announces that the metal controller in Ottawa has rationed 400,000 sap pails to be available for the spring season of 1941. At this rate, he would not see the end of the replacement operation. Vaillancourt had reached an agreement with the two governments to subsidize the cost of the pail replacement program being administered by the Cooperative. The producers must turn in their old sap pails and pay a third of the cost of the new pails with the federal and provincial governments each picking up a third of the remaining cost.

In December 1942, the L’Hoir company obtains a letters patent, and forms a corporation under the name “Les Produits en Aluminium et Acier Inoxydable L’Hoir Inc.” to “manufacture, buy, sell, and import all kinds of products, articles, and merchandise in metal and conduct trade in general and in particular engage in transactions directly or indirectly, to industry or commerce, for objects manufactured from aluminum or stainless steel”. In 1943, Vaillancourt obtains a better position to affect the supply when he became and advisor to the wartime price commission.

When the war is over, aluminum becomes abundant again and industry experiences unexpected economic growth. The L’Hoir factory continues to produce maple syrup equipment as well as lightweight saucepans that are popular with housewives. However, their founder dies in 1948, leaving his son Georges in charge of the company.

During the 1950s, larger and larger objects are coming out of the factory. The factory produces tanks of all kinds and shapes, fixed and mobile, that are intended for different liquids, such as alcoholic beverages, dairy products, vinegars, and other food products. In the case of sap pails, the replacement program comes to an end in March 1960. In all, about 18 million sap pails were made at L’Hoir, before plastic begins to see increased use in the maple industry.

In 1984, the company experienced difficulties and was sold in a last-ditch attempt to save it from bankruptcy. Ultimately, the factory closed its doors and looked for a new tenant and use. The house where Louis Fréchette was born remains uninhabited since 1985 and its fate remains uncertain. On November 11, 2000, Georges L’Hoir died at the Hôtel-Dieu in Lévis. His factory was demolished a few years later and the sale of the property remains unfinished. Ironically, Georges L’Hoir’s Belgian factory in Angleur, near the center of Liège, still partly exists, and is currently occupied by Drytec, a pneumatic industrial company.

“Our home was not precisely rich, but its relative elegance contrasted with most other houses in the neighborhood. I still see her in her frame of old hairy elms, with its green shutters, on a white background, its veranda, and its vegetable garden. “(Louis-Honoré Fréchette)

Thanks to L’Hoir’s expertise, maple products have seen a significant reduction in lead contamination. Since that time, the lead content in maple syrup made in Quebec is tested. If the concentration is too high, above 250 parts per billion, the maple syrup is destroyed. Aluminum sap pails are now antiques. Nevertheless, they are still widely used and recognized by almost any Quebecer whether they are being used for maple syrup or not.
