Project Gutenberg 1997-07-01 Public domain in the USA. 452 Munro, John 1849 1930 Heroes of the Telegraph Produced by An Anonymous Volunteer, and David Widger "Heroes of the Telegraph" by John Munro is a historical account likely written in the late 19th century. The book explores the lives and significant achievements of key figures in the development of the electric telegraph and telephone, highlighting their contributions to electrical science and communication technology. The opening of the book introduces the concept of invention as a complex organic process, suggesting that the electric telegraph was the result of cumulative efforts from various inventors rather than the accomplishment of a single individual. Munro notes that the book serves as a sequel to "Pioneers of Electricity," providing a narrative journey through the history and origins of the telegraph. The first chapter delves into early scientific discoveries related to electricity and magnetism, laying the groundwork for subsequent discussions about figures like Charles Wheatstone and Samuel Morse, who played pivotal roles in making the telegraph a practical tool for communication.
