Scientist Robert Klark Graham, 90, Dies

SAN DIEGO - Robert Klark Graham, who believed intelligence could be bred and established a sperm bank that originally accepted sperm only from Nobel Prize winners, died Thursday. He was 90.

Graham died at the meeting of the American Association for the Advancement of Science in Seattle. He was found in his hotel-room bathtub after hitting his head in a fall, said his wife, Marta Everton Graham.

Graham was also a renowned optical physicist who developed shatterproof eyeglass lenses.

His Repository for Germinal Choice takes credit for fathering more than 212 children since it opened in 1980 in Escondido, Calif.
