2267 Agassiz           Discovered 1977 Sept. 9 at Harvard College Observatory, Agassiz Station.
Named in memory of Jean Louis Rodolphe Agassiz (1807-1873), Swiss-born naturalist, later a professor at Harvard, where he was the leading U.S. opponent of Darwin; his son Alexander Agassiz (1835-1910), marine zoologist and oceanographer; and his grandson George Russell Agassiz (1862-1951), for many years a friend and benefactor of the Harvard Observatory and for whom the Agassiz Station is named.
