From Wiki on Ewald: “When Erwin Schrödinger let it be known that he was leaving his position as extraordinarius professor at the Stuttgart Technische Hochschule, Ewald was called and accepted the position in 1921. In 1922, he was called to the University of Münster...Also in that year, Ewald became co-editor of Zeitschrift für Kristallographie. In 1929, he received a call to the Technische Hochschule Hanover...and (i)n 1931, Ewald was appointed Director of the Physical Science Division...”
“The main thrust of Ewald’s work was X-ray crystallography, and Ewald was the eponym of Ewald construction and the Ewald sphere, both useful constructs in that field.”
“He emigrated to England in 1937 and took a research position in Cambridge, until he was offered and accepted a lectureship at Queen's University Belfast, in 1939... in 1944, at Oxford, he proposed the establishment of an International Union of Crystallography (IUCr) that would have sole responsibility for publishing crystallographic research...In 1952, Ewald was elected President of the American Crystallographic Association...A decade after moving to Belfast, Ewald moved to the United States in 1949 and took a position at the Polytechnic Institute of Brooklyn, as a professor and head of the Physics Department. He retired as head of the department in 1957 and from teaching in 1959.”
