Leblanc, Jean

Fortunately for a poor, would-be chemist like Leblanc, France s aristocratic passion for the physical sciences crossed economic, social, and political borders. Intellectuals such as Rousseau and Diderot cultivated the sciences with enthusiasm and compiled encyclopedias and dictionaries of natural substances. Local academies and institutes in the far-flung provinces sponsored chemical studies. Crowds flocked to hear chemists lecture and to watch their flashy laboratory demonstrations. Even the future revolutionary, Jean-Paul Marat, experimented with fire, electricity, and light and tried—in vain—to become a member of the Royal Academy of Sciences. In America, Benjamin Franklin abandoned his printing and publishing business for physics, and in England his friend Jane Marcet wrote Mrs Marcet s Conversations in Chemistry for women and working-class men. 

In the midst of the excitement, Leblanc told his former chemistry professor, Jean Darcet, the fabulous secret of his discovery. After running some tests and confirming Leblanc s discovery, Darcet recommended it to their patron, the Duke of Orleans. So far the process had worked only in laboratory crucibles, but Darcet declared optimistically, I the undersigned, professor of chemistry at the Royal College of France and at the Royal Academy of Sciences, etc., certify that. . . with this same process, it will be easy to establish a factory. As is often the case, reality proved to be a trifle more complicated.

The discovery was only part of the importance of Leblanc s contribution. He also commercialized the technology. Leblanc built his leading-edge technology facility at the La Franciade works in St. Denis, outside of Paris in 1791. Partners in the venture were Louis Philip 11, the Duke of Orleans (1743 - 1793), Michel Jean Jerome Dize (1764 - 1852) and Henri Shee. The small facility, measuring 10 X 15 meters, produced 0.25 tonnes per day of soda ash. Unfortunately for the inventor and his partners, France was soon in the turmoil of the Revolution, and the major investor was on the wrong side. By the order of the Committee of Public Safety, the facility was confiscated by the state in 1794, not because of Leblanc,...
