- Professor Liedenbrock is a passionate and impatient mineralogy professor who teaches at the Johannæum in Hamburg, Germany.
- He has a tendency to get angry during his lectures due to his difficulty pronouncing long scientific words, which often results in him swearing. This amuses the students.
- While he has a bad temper and can be rough in his handling of specimens, he is a very learned man with a deep knowledge of mineralogy and geology.
