George Coy

George Coy was an influential inventor and businessman known for his pioneering work in the development of telephone technology. In January 1878, he established the first commercial telephone exchange in New Haven, Connecticut, which allowed multiple users to connect through a central switchboard, revolutionizing communication. Just a month later, on February 21, 1878, his company published the world's first telephone directory, listing the names of 50 subscribers without any phone numbers, reflecting the early stage of telephone use. Coy's innovations laid the groundwork for modern telecommunications, transforming the way people connected and communicated.
