The story
Lewis is the English spelling of Louis, and behind both stands an old Germanic name meaning famous warrior, burnished by eighteen kings of France. In its English form it belongs to storytellers and scientists alike, from Lewis Carroll to Lewis Latimer, the inventor born to parents who had fled slavery, who taught himself mechanical drawing, drafted the patent drawings for Alexander Graham Bell's telephone, and then devised a better way to make the carbon filaments that turned electric light from a luxury into an everyday fact, earning his place among the honored Edison Pioneers. The American chart tells a tidy story: Lewis was a solid presence through the early twentieth century, eased off during the 1980s and 1990s, and has been climbing again since, lately matching its old strength. Traditional names rarely get second acts this convincing, and Lewis is enjoying every page of its own.
