On March 10, 1876, Alexander Graham Bell made the first phone call, transmitting the words "Mr. Watson, come here, I want you" over a copper wire to his assistant in the next room. 150 years later, AT&T is commemorating this milestone with a pop-up exhibit at its Dallas headquarters featuring the original copper wire, Thomas Watson's notebook, and Bell's pioneering "photophone" invention. While technology has advanced dramatically, the desire for real-time, one-on-one connections remains.

Why it matters

The first phone call marked the birth of an industry that has transformed how people communicate over long distances. Though voice calls now make up a small fraction of overall digital traffic, the need for personal, focused connections remains as relevant today as it was 150 years ago. This anniversary highlights the lasting impact of Bell's invention and the human desire for meaningful interactions, even as communication methods continue to evolve.

The details

The exhibit at AT&T's Dallas headquarters showcases key artifacts from the first phone call, including the original copper wire, Thomas Watson's notebook, and Bell's patent for the "photophone" - an early precursor to fiber optic technology that transmitted voice over light. While the telephone occupied Bell for only a few years, he continued experimenting and viewed the photophone as his greatest invention. The exhibit also features the original transistor, which Caughlin calls "the second greatest invention that ever came out of AT&T" and underlies most modern electronics.
