The Conklin Pen Company was founded in 1898 in Toledo, Ohio, by Roy Conklin. Initially, the company produced mechanical pencils and dip pens, but in 1901, Conklin introduced its first fountain pen, the Crescent Filler.

The Crescent Filler was unique because it featured a crescent-shaped filling mechanism that was easy to use and prevented ink spills. The user would simply turn the crescent knob on the pen to draw ink into the barrel, and then turn it again to expel excess ink and create a vacuum seal.

The Crescent Filler was an instant success and became one of Conklin's most popular pens. It was so popular that it was used by Mark Twain, who famously endorsed the pen, saying that it was "the only pen that can write upside down".

Conklin continued to innovate and improve its fountain pens over the years, introducing new designs and filling mechanisms. more...
