Of all the great minds to inhabit Washington, D.C. through the years, perhaps one of the most consequential yet often overlooked, was Alexander Graham Bell. Though his famous 1876 telephone experiment took place in Boston, Bell moved to the District shortly thereafter and worked on what he considered to be his greatest inventions in several Northwest labs over the next few decades. Of his many D.C.-based achievements, perhaps the most significant occurred at his small lab on L Street and led to the eventual birth of fiberoptic communication.
