Rudolf was born in Munich, Germany, graduated with distinction in physics at the Ludwig-Maximilians Universität, and completed his doctorate on star formation at the Max Planck Institute for Astrophysics. 

He followed the call to become a senior management consultant in London, where he advised the financial services industry for nearly ten years. 

His passion for the Tango tempted him to Buenos Aires where he studied psychology and sociology at the Universidad de Palermo. Rudolf is chiefly drawn to evolutionary and depth psychology (the school of Carl Gustav Jung). 

His travels have taken him to the Middle East, Asia, and Africa, but he feels most at home in Latin America. The globetrotter speaks three languages fluently, convinced that the language of the heart is the most important one. He has written several travel guides suitable for Expats, globetrotters, and students.

Rudolf suffered a life-threatening stroke in 2023 (right hemisphere Thalamus). He survived, but since then, his left side is paralysed. He now travels the world in a wheelchair. His speech is somewhat impaired, but his laughter is still heartwarming: "If there is nothing you can do about, go to the Pub, have a pint and a good laugh."
