context_page_description: Isaac Peral y Caballero, was a Spanish engineer, naval officer and designer of the Peral Submarine. He joined the Spanish navy in 1866, and developed the first electric-powered submarine which was launched in 1888, but it was not accepted by political authorities, but it was accepted by the naval. He then left the navy to develop other inventions commercially.
context_section_description: Isaac Peral, frustrated with the group of senior naval engineers that were supposed to supervise his project, retired from active naval duty in November 1891. He established his family in Madrid, founding an electric company and still inventing and patenting other inventions, such as an electric machine gun or the blueprints of the first electric power plants of Spain. He still was hoping that his submarine design would be adopted by the government at any moment.
  After an operation in Berlin to cure the brain tumor he had been suffering from for some years, Peral contracted meningitis. He died from it in Berlin in May 1895. Initially buried in Madrid, in 1911 his body was relocated to Cartagena, where there is now a museum devoted to his persona and inventions.
