Why was Woodrow Wilson nicknamed the schoolmaster?

Woodrow Wilson was nicknamed "the schoolmaster" due to his academic background and teaching style. Before becoming the 28th President of the United States, he served as a professor and president of Princeton University, where he emphasized education and intellectual development. His methodical approach to governance and his focus on reform and moral leadership further reinforced this nickname, as he often treated political issues with the same rigor and discipline as a classroom.
