Le Radium congolais et canadien
Softcover 21 pp. Stapled. Folding map of Canada (Hunter Bay, Echo Bay) and map of Katanga (Shinkolobwe, Luishia). Signed by the author. Note LT: This paper (in French) discusses the price levels of Kantangese and Canadian radium (pechblende, uranium). Although Laude indicates "Shinkolobwe" on the map, he speaks of "Chinkolobwe" (sic!) in the text. This misspelling of the name of the mine persists in later history books. Even today journalists misspell the name. In the computer era this leads to false results in search operations (e.g. on the internet, libraries, ...). Research should pay attention to this detail.
The article pays attention to the global network of Union Minière.
The links with the scientific branches in the US facilitated the work of Edgar Sengier when he sold the necessary quantities of uranium to the US Army. One might even say that the preparations for the atomic bomb were made long before the outbreak of World War II.
Laude points at the importance of the harbour of Lobito and the railway through Angola, colonial property of Portugal. Indirectly Lissabon became gradually a center for secret negociations concerning uranium transits.
