Lewis Waterman, an insurance salesman in New York City, invented the first truly functional fountain pen in the early 1880s. A typical pen of the day leaked all over a contract he had prepared for a large policy, and by the time Waterman returned with a new document, his client had signed with someone else. Later, Waterman was working as a pen salesman in New York for a new company founded in the spring of 1883 by a volatile inventor named Frank Holland. Holland abandoned his company after only six weeks; Waterman stepped in and took over, fitting the pens with a simplified feed of his own design. It was for this "three fissure feed" which his first pen-related patent was granted in 1884.
