From Prague, Einstein took the train to Vienna, where three thousand scientists and excited onlookers were waiting to hear him speak. At the station, his host waited for him to disembark from the first-class car but didn’t find him. He looked to the second-class car down the platform, and could not find him there either. Finally, strolling from the third-class car at the far end of the platform was Einstein, carrying his violin case like an itinerant musician. “You know, I like traveling first, but my face is becoming too well known,” he told his host. “I am less bothered in third class.”
