Politician, diplomat, and naturalist Spanish, born in 1745, is not known to science certain if in Navarra and Zaragoza, and died in France, near Paris, 29 May 1813.
Although he came from a humble family, he got out of the darkness thanks to the protection of the count of Fuentes, who tractor you studying. So, in 1779 he was in Paris to study natural sciences, and the following year goes to Vienna with the same mission (in particular the study of the mines), but soon returned to Paris, where befriends Olavide and Buffon, whose Histoire naturelle translated partly Lacépède and other French savants. Without being diplomatic professional, from 1782 he leads with the count of Castries, the French Minister of marine, negotiations for a Treaty of commerce between Spain and France.
During the Ministry of Grimaldi(1792-1798), travel across Europe as director of the Royal Cabinet of Natural history, with various official missions. At the same time, it establishes several sheets of copper, in Jubia (Coruña), factories in Algeciras and Romilly-sur-Andelle, near Rouen. In 1786 he negotiates with the Bank of San Carlos, to represent, along with Augustin Queneau, House Lecoulteulx and Cia.
After play several diplomatic missions that the Ministers Floridablanca, Lerena and Valdés, commissioned in November 1797, already over fifty years, he travels as a secret agent of Godoy to Paris, where it would arrive in January of the following year. He soon realizes that some people thought of it that had Republican leanings and that his mission had been discovered, so, after an interview with Talleyrand on 14 March 1798, he departed for Normandy. The next day, March 15, the Board expelled him from France and granted twenty days to leave the country by the Spanish border, since otherwise it would be treated as a spy.
Back in Madrid, in 1804 Godoy sent him back to Paris, in a mission that, this time, ended up in the tragedy of 1808. It should be noted that, from the political point of view, left deeply admired Bonaparte, and that at the same time their patriotism was unquestionable at the beginning its purpose was surrounded by the most impenetrable secret: not even the Kings knew what was going to be left in Paris. Finally, on June 4, 1804, Godoy speaks with him and reveals his projects: form an independent in Portugal, with the help of Napoleon Principality, because the delicate situation in the Court and the dangers lurking in this you make it feel threatened. A year later it would sign the Treaty of Fontainebleau, which distributed Portugal between France, Spain, and the Prince of peace treaty that finally was without effect.
Left immediately puts hands to work to work, without great results at the beginning. His relationship with the official Ambassador, Gravina, became strained, although already at the beginning of 1805 they had become accustomed to the other, because left knew well the Spanish Navy, which was a supplier. In 1806, he joined the Supreme Council of war, and sees how things fall.
In order to gain the friendship of Napoleon, knowing that this worry about the Prince of peace if he gave him the pecuniary help desiring both, may 10 gave him 24 million francs belonging to caixa de consolidation de Madrid - without being authorized to do so-, measure adopted by Godoy, who made him honorary State Councillor and got that Carlos IV gave him the 26th full powers to negotiate a treatywhich included their participation in high financial matters.
Prior to this, on March 14, it had signed an agreement with Michel Jeune, whereby Spain is forced to pay 411 bills of Exchange, from the purchase of grain carried out the previous year by the consolidation box. The fact was that the 10th capital came from the Commission obtained for the estimation of debt consolidation box with Ouvrard and his group, at a date which was not appropriate to the interests of the box.
Faced with protests in this institution, he did see that this test of goodwill would enable Vanlerberghe Ouvrard retain their status as suppliers of army and Navy French, enabling them to pay off their debt with the box. It is suspected that there were certain special relationships between the parties explaining the public attitude of left. In 1807 they continued dealings with Vanlerberghe Ouvrard and Mollien, Minister of the Treasury, which also intervened Michel Jeune who on 17 September 1806, had been appointed general banker of Spain in Paris. From the economic point of view, all this shows inability to Spanish shake the French tutelage.
Anticipating what was going to happen, left then bought a property near Bordeaux. At the beginning of 1808 is Napoleon who sent him to Spain, but then left, who knows the imperialist projects of Napoleon with respect to Spain, is completely daunted. From Paris arrives in Madrid on 5 March and was immediately meets Godoy, together to March to Aranjuez to greet Kings and reveal to them the projects of Napoleon. Returned to Paris on March 19, 1808, with the real response to the proposals of Napoleon: title of Emperor of America for Carlos IV, trade concessions, which would be the future King Fernando VII, marriage as well as the important issue of the transfer or the independence of the left bank of the Ebro. Seeing the situation, and by governing left, transfer was agreed of the Royal family to Cadiz, where plan for America - travel which, as it is known, did not occur.
The mutiny of Aranjuez cut all these speculations. Izquierdo was present at the abdication of Bayonne, after which Carlos IV went to France, left as Secretary with yours to courageously defend their real interests against the French Government; She had harsh words against Napoleon, who made him watch by the police. He bequeathed his papers to Godoy, although this did not receive them until August 1814, a year after his death.
