Life

Back to 1900 Ernst visited the school in Strasbourg and closed it from 1902 to 1906 studying law in Strasbourg, Munich and Berlin. Until 1909 he worked in Alsace -Lorraine in the field of jurisprudence. He then took leave and started studying physics in Tübingen. In 1912 he gave up the legal profession and earned his doctorate degree in 1913. His doctoral thesis, which he wrote to Presto 's rule under the title, dealt with the phenomenon that later became known as the Paschen-Back effect and is named after him and Friedrich Paschen.

In the years 1914 to 1918, he served in the German army during the First World War. After the war, he headed the Laboratory of Veifa works in Frankfurt am Main. The company donated electrical equipment and x-ray equipment manufactures. In 1920 he left the company and took a job as assistant at the Physics Institute in Tübingen. In 1926 he received a professorship at the University of Hohenheim and as a result, he became in 1929 the chair. This he held until 1936, when he returned to Tübingen, there to accept a professorship.

From 1926 to 1927 he worked with Samuel Abraham Goudsmit on the first measurements of the electron spin and the associated Zeeman effect. Back in 1948 Ernst retired and died in Munich more than ten years later.

In 1976 the crater was named Back on the moon after him.
