Waterman
Lewis Waterman’s company in New York, with the feed that made the fountain pen reliable; later based in France.
Lewis Edson Waterman was an insurance salesman in New York who developed a feed that gave an even flow of ink. Waterman became one of the largest pen makers in the United States.
The French branch became the headquarters after the American business declined, and pens such as the Patrician of 1929 became classics. Waterman is now part of Newell Brands.
Ideal and Waterman’s stamped on the barrel of early pens; black or mottled ebonite.
