He became renowned for his inventions of the first mechanical pencil (1906) (then called "automatic pencil") and the first solid-ink fountain pen (1907). Together with an enterpreneur by the name of Edmund Moster, he started a factory of pens and pencils "Penkala-Moster" that was one of the bigger in the world at the time, and still exists today (named "TOZ-Penkala", where TOZ stood for "Tvornica olovaka Zagreb", meaning "Zagreb pencil factory").
