Content: Why did we need electrical telegraphs before the telephone? Well, both the telephone and the telegraph are wire-based electrical systems. The telegraph also paved the way for later telephone inventors. As About.com explains, “Alexander Graham Bell’s success with the telephone came as a direct result of his attempts to improve the telegraph.” By the time Bell began experimenting with using electrical signals to send audio data, the telegraph has been an established means of communication for nearly three decades. Limitations of the Telegraph: Why Did We Need a Telephone? One of the more puzzling parts parts about the invention of the telephone (at least to our modern way of thinking) is that when Bell first showed off his telephone, many people argued that we didn’t actually need such a device. Why would you want to hear someone’s voice when you could just send them a telegram instead? The truth is, the telegraph was an extremely limited system.
