Ginsparg

Ginsparg is an American theoretical physicist and information scientist who serves as a professor at Cornell University. He is best known for creating arXiv, an open-access e-print repository for physics and related disciplines. The project began in 1991 at Los Alamos National Laboratory to accelerate the distribution of scientific papers and has grown into one of the most widely used platforms for preprints, with thousands of submissions daily.

In lattice gauge theory, the Ginsparg–Wilson relation is named after him and Kenneth G. Wilson. The relation expresses a condition on lattice Dirac operators that preserves a form of chiral symmetry, enabling more accurate simulations of quantum chromodynamics.

Ginsparg's work has significantly influenced scholarly communication and open-access practices in physics and beyond. His contributions helped redefine how scientific results are disseminated, facilitating rapid sharing and broad accessibility across the research community.
