Rufus Oldenburger

Rufus Oldenburger (Grand Rapids, 6 de julho de 1908 – 1969) foi um matemático e engenheiro mecânico estadunidense.^[1]

Oldenburger obteve um doutorado na University of Chicago em 1934.^[1][2]

Foi palestrante convidado do Congresso Internacional de Matemáticos em Oslo (1936).

Em 1968 foi o primeiro recipiente da Medalha Rufus Oldenburger.
