As First Officer of Venezuela's Foreign Secretariat after the coup on April 19, 1810, he was sent to London with Simón Bolívar and Luis Lopez Mendez serving as Diplomatic Representative to procure funds for the revolutionary effort until 1813. Bello landed at Portsmouth as an attache to Bolivar's mission in July 1810. Bello had an admittedly hard life throughout his stay in England, though he managed to further develop his ideas and took a particular interest in England's social changes from the industrial and agricultural revolution. In order to earn a living while in London, Bello taught Spanish and tutored Lord Hamilton's children. In London, he met Francisco de Miranda and became a frequent visitor of his library in Grafton Way, as well as of the British Museum. During his lengthy stay in England, he curbed his feelings of homesickness and became contemporaries with thinkers and intellectuals such as José María Blanco White, Bartólome José Gallardo, Vicente Rocafuerte to name a few. He stayed in London for nineteen years acting as a secretary to legations and diplomatic affairs for Chile and Colombia. In his free time he was involved in study, teaching and journalism. An English Heritage blue plaque commemorates Bello at 58 Grafton Way, his Fitzrovia address.
