Absalon Larsen was originally MSc. Philosophy and taught theology, then he began to study physics. He subsequently joined to assist Professor Peter Kristian Prytz in the organization of a new exercise course in electronics for mechanical engineers. He was employed at the Polytechnic college, first as a lecturer, later as a professor of electrical engineering. From 1937 he was chairman of the electrical engineering group under the Danish Academy of Technical Sciences.[3]
