Conversation so far:
Did Piet Mondrian paint at all in the Netherlands?
After a strict Protestant upbringing, in 1892, Mondrian entered the Academy for Fine Art in Amsterdam. He began his career as a teacher in primary education; he also practiced painting.
Are there any other interesting aspects about Mondrian's time in the Netherlands besides practicing painting there?
While Mondrian was visiting the Netherlands in 1914, World War I began, forcing him to remain there for the duration of the conflict.

Question: Did he have any influences?
