He took his Doctor of Philosophy there in 1927 under Friedrich Meinecke, and received his Habilitation in 1932, despite strong conservative opposition.
The result of this was a "stunningly original work" on the world economic crisis of 1857-1859, published in Stuttgart in 1934. They were forced into exile and he became one of many refugee historians. He endeavoured to obtain employment, without success, in England, before finally emigrating to for the United States in 1935.
He taught briefly at Illinois College before taking a position at Brooklyn College, where he was to teach undergraduates for 23 years.
Among his most distinguished pupils there was Raul Hilberg. His work identified in the power structures and social relations of agrarian society in Prussia the roots of the authoritarian and undemocratic character of what he, with others, took to be the Sonderweg, or special path of modern German history.
He taught briefly, for a year (1949–1950) at the Free University of Berlin, and then at Marburg in 1955. His influence on the young generation of German historians has led to the claim he was the father of modern social history (Gesellschaftsgeschichte in post-war Germany.
From 1959 to 1972 he taught at Berkeley and crowned his career as Shepard Professor Emeritus.
To this period is dated his classic work, which he reworked for his classic The Great Depression of 1873-1896 in Central Europe (Grosse Depression und Bismarckzeit, 1967). He retired in 1972, and returned for personal reasons to Germany in 1977, settling in Kirchzarten near the University of Freiburg, where he had been appointed Honorary Professor the year before. He was awarded the Bundesverdienstkreuz, Ist class by the Federal Republic in 1979.
He died in 1988, aged 84.

As the Great Depression unfolded, his attention shifted from the history of ideas and nationalism, which he studied under Meinecke, to economic cycles. Faculty politics at Cologne, the rise of Nazism and his Jewish ancestry, made the prospect of any career in Germany improbable both for him and his wife Helen (Leni), a promising concert pianist.
