In 1891, Roy Conklin received a patent for his fountain pen design. Later, in 1898, he began the Conklin Pen Company in Toledo, Ohio. During 1916, the pen innovator produced a spring-loaded pocket clip, and later in the 1920s, Conklin started sending his pens overseas to Europe and South America. In 1921, Conklin's Crescent Filler model became the market's top selling product. The company released a lever-filling version after the Sheaffer Pen Corporation experienced success with its Lever Filler writing device. In 1923, Conklin introduced the Duragraph model, which led to the company producing the Endura edition during 1924.
