1880–1960
A leading American mathematician of the early 20th century, he helped shape modern geometry and topology and later played a key role in founding the Institute for Advanced Study in Princeton.

by N. J. (Nels Johann) Lennes, Oswald Veblen
Born in 1880 and educated at the University of Iowa and the University of Chicago, he built his reputation through important work in geometry and topology. He spent much of his career at Princeton University, where he taught mathematics and became one of the field’s most influential figures.
He is especially remembered for advancing the study of manifolds and for work that connected pure mathematics with later developments in physics. Beyond his research, he also served the mathematical community through leadership roles, including work with the American Mathematical Society.
In 1932, he left Princeton University to become the first professor appointed at the newly organized Institute for Advanced Study, helping establish it as a major center for research. He remained associated with the Institute for the rest of his career and died in 1960.
