. Rohrer measured the length changes of superconductors at the magnetic-field-induced superconducting transition, a project begun by Jørgen Lykke Olsen. In the course of his research, he found that he had to do most of his research at night after the city was asleep because his measurements were so sensitive to vibration. His studies were interrupted by his military service in the Swiss mountain infantry. In 1961, he married Rose-Marie Egger. Their honeymoon trip to the
