"Pierre-Augustin Caron de Beaumarchais (French: [pjɛʁ bomaʁʃe]; 24 January 1732 – 18 May 1799) was a French polymath. At various times in his life, he was a watchmaker, inventor, playwright, musician, diplomat, spy, publisher, horticulturist, arms dealer, satirist, financier, and revolutionary (both French and American).
Born a provincial watchmaker´s son, Beaumarchais rose in French society and became influential in the court of Louis XV as an inventor and music teacher. He made a number of important business and social contacts, played various roles as a diplomat and spy, and had earned a considerable fortune before a series of costly court battles jeopardized his reputation." - (en.wikipedia.org 30.10.2019)
