Henri Eyraud (1892-1994). Studied mathematics at the
University of Paris and received his doctorate in 1926 with a
thesis on “Metrical spaces and physico-geometrical theories”. From
1930 professor of mathematics at the University of Lyon and
director of the Institute of “Financial and Assurance-Sciences”.
Perhaps he considered his papers on the geometry of unified field
theory as a sin of his youth: In Poggendorff, among the 33 papers listed, all
are from his later main interest.
