Book Description
The single-wire telegraph revolutionized long distance communication but it was not the brainchild of one inventor, Samuel Morse. His colleagues and employees--specifically Ezra Cornell and Joseph Henry--made crucial contributions. Examining the careers of the three men and the key events, this book presents Morse as primarily a businessman and consolidator of ideas who, frequently in conflict with his associates, sought to present the telegraph as a uniform system under his sole imprimatur. The battle between Morse and Cornell over the invention of the magnetic relay was central to the drama. What emerges is a complex portrait of three ambitious and brilliant innovators and the age in which they lived.

Book Description
Writer Tracy Nelson Maurer and illustrator El Primo Ramón present a lively picture book biography of Samuel Morse that highlights how he revolutionized modern technology. Back in the 1800s, information traveled slowly. Who would dream of instant messages? Samuel Morse, that’s who! Who traveled to France, where the famous telegraph towers relayed 10,000 possible codes for messages depending on the signal arm positions—only if the weather was clear? Who imagined a system that would use electric pulses to instantly carry coded messages between two machines, rain or shine? Long before the first telephone, who changed communication forever? Samuel Morse, that’s who! This dynamic and substantive biography celebrates an early technology pioneer.
