toothpasteIn the early 1940s, the U.S. was at war and extraordinary efforts were underway to build an atomic bomb. The government even went so far as to confiscate the uranium oxides used by ceramics manufacturers to produce red/orange glazes. More than a few collectors must have been upset at the disruption in their supply of red dinnerware. Still, sacrifices were required. Similar confiscations occurred in occupied Europe to supply the Nazi A-bomb project, and keeping track of Germany’s atomic research was an allied intelligence effort code-named Alsos (the Greek word for grove, as in General Leslie Groves).

Doramad Radioactive Toothpaste was produced during World War II by Auergesellschaft of Berlin. The same company founded by Carl Auer von Welsbach invented the gas lantern mantels..

Doramad Radioactive toothpaste. Biologically effective cleaning • Germ Killing Refreshing Auer Gesellschaft Aktiengesellschaft Chemistry Department. Berlin N 65.

In the fall of 1944, the Alsos team learned that Auer Gesselshaft, a German chemical company involved in securing and processing uranium, had taken over the French company Terres-Rares (rare earth elements) during Nazi occupation. Ominously, Auer had shipped Terres-Rares’ massive supply of thorium to Germany. That the Germans wanted thorium suggested that their atomic research was further advanced than previously thought. Shortly after Paris was liberated, the Alsos team converged on the Terres-Rares office. They found it empty. Petersen, the Auer company chemist involved in securing the uranium and thorium supplies, had fled the allied advance. (in Now It Can Be Told, Leslie Groves in gives this man the name Jansen).

Doramad brochureThe back of the tube reads: How does Doramad work?
Through their radioactive radiation increases the defenses of it tooth and gums. The cells are loaded with new life energy, inhibited the bacteria in their destructive effect. Therefore, the excellent preventive and curative effect on gum disease. Polished enamel on the most gentle white and shiny. Prevents tartar approach. Lathers beautifully, tastes new, pleasant, mild and refreshing. Extensively in use.

Petersen had gone to a town on the French-German border searching for some missing railroad cars carrying the thorium. And, as luck would have it, the area was captured by the allies shortly after Petersen arrived. Alsos had their first prisoner—and a suitcase bulging with documents! Among these was a dossier on a businesswoman who plied the world’s oldest profession sur les rues de (on the streets) of Paris. Petersen’s explanation for having the dossier was that the woman had charged him an exorbitant 3000 francs although “in Berlin . . . it is only seven marks and a half per fling.” He said he was hoping to contact the proper authorities (whoever they would be) to recover some of his money. When the Alsos investigators took to the streets, they found that all aspects of Petersen’s implausible story proved true. However, the suitcase’s most shocking document revealed that Petersen had recently visited Hechingen, a town rumored to be a center for atomic research. Later it would be learned that the Germans had a lab there with an isotope separation unit and, in a nearby cave, an experimental pile. When the site was eventually captured, a ton and a half of metallic uranium cubes from the pile (likely produced by the Auer company) were found buried in a nearby field. Petersen’s explanation for his trip to Hechingen: he was visiting his mother (no doubt seeking advice on how to recover his 3000 francs). Darn thing was, his mother actually lived there.

doramad3Ultimately, Alsos’ hard work paid off and they discovered the true reason why Terres-Rares’ thorium supplies had been confiscated: the Auer Company, recognizing that the end of the war was near, and concerned about the consequent loss of business, concluded that there was no better future for their company than in cosmetics and related consumer products! doramad4Radium had already been used in toothpaste (Radiogen), why not use thorium instead? Auer had the patent, and with the thorium in hand they were ready to hit the ground running. They even formulated the following potential advertisement: “Use toothpaste with thorium! Have sparkling, brilliant teeth—radioactive brilliance!”
