Nicholas Callan and experimental philosophy under Dr. Cornelius Denvir. He introduced the experimental method into his teaching, and had an interest in electricity and magnetism. Callan was ordained a priest in 1823 and went to Rome to study at Sapienza University, obtaining a doctorate in divinity in 1826. While in Rome he became acquainted with the work of the pioneers in electricity such as Luigi Galvani (1737–1798) who was a pioneer in modern obstetrics and Alessandro Volta (1745–1827) who is known especially for the development of the electric battery. In 1826, Callan returned to Maynooth as the new Professor of Natural Philosophy
John Read (inventor) after his death. John Read (inventor) John Read was a British physicist and inventor. He developed a rotating doubler electrostatic generator, used to produce static electricity, which he called a 'spectacle doubler' because it involved discs of glass. His work was based on William Nicholson's doubler. Reid lived in Knightsbridge, London and taught at the Knightsbridge Charity School. He made observations of the atmospheric electric field, which he observed behaved differently in different air quality conditions, in 1791 and 1792. This phenomenon is now understood as originating from the global electric circuit. Richard Lovett was the first British academic to
