Jean Vesque de Puttelange (12 November 1760 – 1 March 1829), born in Brussels, was a government official of the Holy Roman Empire, serving in administrations in the Habsburg Netherlands and Vienna.
On 17 March 1793 Archduke Charles, Duke of Teschen became Governor of the Habsburg Netherlands and Vesque returned to Brussels where - among other functions, he acted as censor of theatres.
[5] The peace only lasted a few months before the outbreak of the War of the First Coalition, which was an attempt by the Triple Alliance (Prussia, Austria and Britain) to defeat Revolutionary France.
With no home to go to, and with dwindling finances, Vesque set off through Germany and Switzerland (mostly on foot), relying on a small pension; he stayed some time in Italy (perhaps including Milan) studying fine art treasures ('Kunstschätze').
The half-starved child was almost lost: her father Prince Alexander, who was in the French Army, heard of her plight, and sent someone to fetch her, who arrived only three days before she was to have been sent to the Foundling Hospital of Paris, the fr:Hôpital Saint-Vincent-de-Paul.
Vesque told the resident French Minister in Vienna, citoyen Champagny,[11] that he wished to be Austrian as one of those « individus belges qui ont déclaré vouloir rester sujets autrichiens » ('Belgian individuals who have declared that they wished to remain Austrian'); he was considered an émigré and his estates and property in Lorraine, in the département des Forêts in Luxembourg, and in Belgium were sequestrated, although he still couldn't get a job in Vienna because on the ban on Austrian-Belgian officials/civil servants.
[6][7] When in 1804 the ban was lifted which had denied the Belgian officials from staying in Vienna, the Lubomirskis, father and daughter, and Vesque moved there straight away.
Rosalie Lubomirski married Count Wacław Seweryn Rzewuski in Vienna that year, and Vesque soon received a court appointment as Royal Secretary ('K.K.
In his capacity as Imperial Treasurer, Vesque appears in the painting of the coronation in 1816 of the Empress Charlotte-Augusta, the third wife of the Emperor Francis II.
[6] He had an equally erudite fecund activity which led him to publish a number of works of literary merit, including poetry, fine art, and archaeology.
