Though having no shortage of romantic conquests, Paganini was seriously involved with a singer named Antonia Bianchi from Como, whom he met in Milan in 1813. The two gave concerts together throughout Italy. They had a son, Achilles Cyrus Alexander, born on 23 July 1825 in Palermo and baptized at San Bartolomeo's. They never legalized their union and it ended around April 1828 in Vienna. Paganini brought Achilles on his European tours, and Achilles later accompanied his father until the latter's death. He was instrumental in dealing with his father's burial, years after his death.
Throughout his career, Paganini also became close friends with composers Gioachino Rossini and Hector Berlioz. Rossini and Paganini met in Bologna in the summer of 1818. In January 1821, on his return from Naples, Paganini met Rossini again in Rome, just in time to become the substitute conductor for Rossini's opera Matilde di Shabran, upon the sudden death of the original conductor. Paganini's efforts earned gratitude from Rossini.
Paganini was introduced to Berlioz in Paris in 1833. Though Paganini also commissioned from him Harold en Italie for viola and orchestra, he never performed it, and instead it was premiered a year later by violist Christian Urhan. Despite his alleged lack of interest in Harold, Paganini often referred to Berlioz as the resurrection of Beethoven and, towards the end of his life, he gave large sums to the composer.
