Paul Thiry, Baron d'Holbach (French: [dɔlbak]; 8 December 1723 – 21 January 1789), known as d'Holbach, was a Franco-German philosopher, encyclopedist and writer, who was a prominent figure in the French Enlightenment. He was born in Edesheim, near Landau in the Rhenish Palatinate, but lived and worked mainly in Paris, where he kept a salon. He helped in the dissemination of "Protestant and especially German thought", particularly in the field of the sciences, but was known more for his atheism and voluminous writings against religion, famously including The System of Nature (1770) and The Universal Morality (1776).
Biography
Sources differ regarding d'Holbach's dates of birth and death. His exact birthday is unknown, although records show that he was baptised on 8 December 1723. Some authorities incorrectly give June 1789 as the month of his death. D'Holbach's mother, Catherine Jacobina (née Holbach; 1684–1743), was the daughter of Johannes Jacobus Holbach (died 1723). His father, Johann Jakob Dietrich (with other notations: ger.: Johann Jakob Dirre; fr.: Jean-Jacques Thiry; 1672–1756), was a wine-grower.
D'Holbach wrote nothing of his childhood, although it is known he was raised in Paris as a Catholic by his uncle Franz Adam Holbach (or Adam François d'Holbach or Messire François-Adam, Baron d'Holbach, Seigneur de Heeze, Leende et autres Lieux; approx. 1675–1753), who had become a millionaire by speculating on the Paris stock-exchange. With his financial support, d'Holbach attended Leiden University from 1744 to 1748, where he became a friend of John Wilkes. In 1750, he married his second cousin, Basile-Geneviève d'Aine (1728–1754), and in 1753 a son was born to them, François Nicholas, who left France before his father died. In 1753 both d'Holbach's uncle and father died, leaving him with an enormous inheritance, including Heeze Castle, Kasteel Heeze te Heeze.
