Invention Development

When: c. 1826
Where: Paris
Part of: Petrache Poenaru receives French patent for the fountain pen

Poenaru invented the fountain pen during his studies at the École Polytechnique, likely in 1826, to facilitate note-taking.

Motivated by the need to copy courses, Poenaru created a pen using a swan's quill as an ink reservoir. The supplied passages do not state an explicit invention date; the 1826 attribution is inferred from his attendance at the École Polytechnique in Paris that year.
