[1] The family relocated to Konstanz in Germany, where his father opened a toy shop.

Following the completion of his apprenticeship, Kreidolf kept working for Schmidt-Pecht as an assistant in order to provide for his family following the bankruptcy of his parents' shop.

On his second application in 1887, the Akademie der Bildenden Künste München accepted Kreidolf as a student.

His work as picture books demonstrates a high level of technical proficiency as well as exact botanical and zoological knowledge.

The Dachshund belonging to Kreidolf's friend and author Leopold Weber, whom he met in Partkirchen, served as inspiration for a large number of quite varied sketches, watercolors, paintings, and a whole illustrated book.
