Personality and Traits

Through decades of experience, Mr. Galvin is very learned in science. He teaches it to his students mostly through lectures, causing student Nate Wright to find him very boring. This is further supported by the fact that he very rarely smiles. He did smile, however, when Nate revealed he was a Timber Scout and when Gina Hemphill-Toms asked if Nate could make it on the honor roll. The only time he ever laughed was at the latter, which was at Nate's expense. He seems to have a degree of emotional instability. This is proven when he was rated "psycho monthly" in Nate's "angergraph." He could occasionally come off as cold and unfeeling, though he is actually selfless, devoting his entire life to teaching aspiring children. He also has a tendency to be honest, even in embarrassing situations. In addition, he is slightly embarrassed about his dentures.


Mr. Galvin is rarely seen smiling. The most recent time he was seen smiling was in Big Nate On A Roll.

He has been teaching at P.S. 38 longer than any other staff. It is possible that Mr. Galvin may have had an experience that stopped him from smiling, however, this is not confirmed.


He has a collection of potatoes shaped like famous scientists. He is also said to have a forty-year-old cologne.[1]
