Alexander Graham Bell, the renowned inventor of the telephone, was a professor at Boston University's School of Oratory from 1874 to 1879. During this time, he conducted pioneering work on the mechanism of speech and the transmission of the human voice over wires, which ultimately led to his invention of the telephone in 1876. BU provided crucial financial and institutional support that enabled Bell to dedicate himself to his experiments, which he later credited as being essential to his success.

Why it matters

Bell's time at BU was a formative period in his career, where he laid the groundwork for one of the most transformative inventions of the 19th century. The telephone went on to "annihilate time and space" and bring the human family closer together, as Thomas Edison famously remarked. Bell's story highlights BU's role in fostering innovation and supporting visionary thinkers.

The details

From 1874 to 1879, Bell was a professor of the mechanism of speech at BU's School of Oratory. During this time, he was working on his "harmonic telegraph" invention, which aimed to transmit multiple telegraph messages over a single wire using different tones. In 1875, BU's School of Oratory Dean Lewis B. Monroe offered to pay Bell's lecture fees in advance, allowing him to focus more time on his experiments. Working in a rented attic room in Boston, Bell and his assistant Thomas A. Watson made a breakthrough on June 2, 1875, when they heard the sound of a plucked reed over the wire. After further tinkering, they were able to transmit recognizable voice sounds, leading Bell to begin drafting the specifications for his first telephone patent, which was issued on March 7, 1876.

What’s next

BU had planned to honor Bell by building a neo-Gothic tower bearing his name as part of a giant cathedral-like complex, but the proposal fell victim to the Great Depression. However, Bell's legacy at the university is still memorialized through the Alexander Graham Bell Professorship of Health Care Entrepreneurship.

The takeaway

Alexander Graham Bell's pioneering work at Boston University laid the foundation for one of the most transformative inventions of the 19th century. BU's support and encouragement were crucial in enabling Bell to dedicate himself to his experiments, ultimately leading to the creation of the telephone and the profound impact it had on human connectivity.
