Education
In 1911, after graduating from high school in Mainz, Vogt enrolled at the University of Heidelberg to study astronomy, mathematics, and physics, where he was under the tutelage of Max Wolf. His studies were interrupted due to World War I, but he continued his scientific career and earned a PhD in 1919 with a dissertation on the topic "On the theory of Algol variables". In 1921, he completed a Habilitation on "Photometric studies and brightness measurements in the cluster h and χ Persei".
