Einar Hille
American mathematician (1894–1980)
Carl Einar Hille (28 June 1894 – 12 February 1980) was an American mathematics professor and scholar. Hille authored or coauthored twelve mathematical books and a number of mathematical papers.
Early life and education
Hille was born in New York City. His parents were both Swedish but never married. His father, Carl August Heuman, was a civil engineer. Hille was brought up solely by his mother, Edla Eckman, who took the surname Hille. When Einar was two years old, he and his mother returned to Stockholm. Hille spent the next 24 years in Sweden, returning to the United States when he was 26 years old. He entered Stockholm University in 1911, and was awarded his first degree in mathematics in 1913 and the equivalent of a master's degree in the following year. He received a Ph.D. from Stockholm in 1918 for a doctoral dissertation entitled Some Problems Concerning Spherical Harmonics.

Why this record matters
“Einar Hille” is worth following because a concise public description often conceals a longer documentary argument. Here, Einar, Hille and American provides the most credible route into that argument.
Chronology provides the most reliable spine for this subject; interpretation should follow only after identities and dates are secure. The source revision retrieved here is dated Aug 31, 2026. The linked authority identifier is Q930705. VIAF identifies the subject as 91737614. The Library of Congress control number is n50035182. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1894, 1980, 1911 and 1913.
Public reputation and documentary evidence do not always develop together; absence from a summary is not evidence of historical absence. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
