means A maker of fine fountain pens, originally famed for solving the leaky-pen problem and turning writing instruments into polished status objects.

from Named for Lewis Waterman, the New York insurance-agent-turned-inventor who, as the well-loved (though embellished) story goes, lost a client after a leaky pen ruined a contract — and so set out in the 1880s to design a reliable feed system that let ink flow evenly without flooding or drying up. Whether or not that lost-sale story happened exactly as told, Waterman's real innovation, a three-channel feed, genuinely fixed fountain pens' worst flaw, and his name became the brand synonymous with the fix.
