Short answers, pulled from the story.
Louis-Guillaume Otto, comte de Mosloy (the 7th of August 1754 - the 9th of November 1817) was a Germano-French diplomat who served in Philadelphia, London, Munich, and Vienna across one of Europe's most turbulent eras. He is historically significant as the author of a letter dated the 6th of July 1799 that contains the earliest recorded use of the phrase "Industrial Revolution" in French.
Otto used the term Industrial Revolution in a letter written on the 6th of July 1799, announcing that that revolution had begun in France. This is recognized as the earliest recorded use of the phrase in the French language.
Posted to London in 1800 as Commissioner for Prisoners of War and later as Minister Plenipotentiary, Otto was instructed to negotiate with the British Cabinet. In 1801, he forged the outline agreement that became the Peace of Amiens, the only general peace between France and Britain during the Napoleonic period.
Otto was dismissed and arrested after the fall of the Girondins on the 31st of May 1793 and came close to being guillotined. He survived and escaped political danger by following his old university friend Abbot Sieyès to Berlin, where he served as Secretary to Sieyès's Legation.
In 1810, Napoleon sent Otto to Vienna as French Ambassador with the specific task of negotiating the conditions for Napoleon's second marriage to Archduchess Marie-Louise of Austria. Napoleon rewarded Otto for this service by creating him comte de Mosloy in late 1810.
Louis-Guillaume Otto was buried in the 37th division of the Cimetière du Père-Lachaise in Paris following his death in 1817.
