A obtinut Premiul Nobel in economie in 1975, impartindu-l cu economistul rus Leonid Vitaliyevich Kantorovich pentru contributiile sale la teoria optimii localizari a resurselor.

Koopmans a studiat fizica si matematica la Universitatea din Utrecht si si-a luat doctoratul in statistica si economie la Universitatea din Leiden. A fost consultant financiar al Societatii Natiunilor de la Geneva (1938-1940). A fost  profesor la Universitatile din Chicago (1946-1955) si Yale.
