Eli Heckscher
Heckscher was born in Stockholm, son of the Jewish Danish-born businessman Isidor Heckscher and his spouse Rosa Meyer, and completed his secondary education there in 1897. He studied at Uppsala University and Gothenburg University, completing his PhD in Uppsala in 1907. He was professor of Political economy and Statistics at the Stockholm School of Economics from 1909 until 1919, when he exchanged that chair for a research professorship in economic history, finally retiring as emeritus professor in 1945. In 1929 Heckscher founded the Institute for Economic History Research.
Eric W. Gritsch
Gritsch was raised in a Lutheran pastor's family in Bernstein im Burgenland in Austria. His family was deeply affected by the "Anschluss" and the Second World War. His father died on a death march as a Russian prisoner of war, but Gritsch himself, who had been drafted into a Werwolf group, escaped capture by posing as a gypsy boy. He returned to Bernstein and graduated with Matura in 1950. The same year, he matriculated at the University of Vienna to study Protestant theology. In 1954 he received a Fulbright scholarship and came to Yale University for the academic year 1954/55. After going back to Austria to complete his ministerial training, he immigrated to the United States in 1957, initially for doctoral studies with Roland H. Bainton. His thesis was on Thomas Müntzer, the radical reformer.
