# Sylvain Van de Weyer

Jean-Sylvain Van de Weyer (19 January 1802 – 23 May 1874) was a Belgian politician who served as the Belgian Minister at the Court of St. James's, effectively the ambassador to the United Kingdom, and briefly, as the prime minister of Belgium, all under King Leopold I.

## Early life

Van de Weyer was born in Louvain on 19 January 1802. He was the son of Josse-Alexandre Van de Weyer (1769–1838) and Françoise Martine (née Goubau) Van de Weyer (1780–1853). He was the grandson of Jean-Baptiste (or Jean-Sylvain) Van de Weyer, who was from a bourgeois family of Bautersem, and Josse Goubeau, commissaire de police de la quatrième section de Bruxelles.
In 1811, his family relocated to Amsterdam. The family returned to Louvain when his father was named police commissioner for the city. Jean-Sylvain studied law at the State University of Louvain and set up as a lawyer in Brussels in 1823.

## Career

As a lawyer, he frequently defended newspapers and journalists that had fallen foul of the government of the United Kingdom of the Netherlands, of which modern Belgium then formed the southern half.
On the outbreak of the Belgian Revolution in 1830, Van de Weyer was in Louvain, but hurried to Brussels where he became a member of the central committee of the Provisional Government of Belgium. His command of the English language resulted in him serving as a diplomatic representative of the revolutionaries. In 1831, King Leopold I appointed Van de Weyer his "special representative" in London. The King at the time was William IV, who reigned from 1830 to 1837, when his niece became Queen Victoria who reigned until January 1901. During his tenure as Minister in London, Van de Weyer became a "beloved and honoured friend of the royal family," as was his wife, who became close to the Queen and comforted her after the death of Albert, Prince Consort.
Van de Weyer later served as the 8th Prime Minister of Belgium, succeeding Jean-Baptiste Nothomb. He was vice-president of the London Library from 1848 till his death in 1874.
He was a founding member of the first Société des douze.
