Donors
Although most news articles of the time made much of the Repository's "Nobel sperm" standards, in fact the Repository is only known to have stocked the sperm of one Nobelist, William Shockley. Other donors were recruited from among the ranks of scientists and academics Graham and his assistant, Paul Smith, considered to be "the future Nobel laureates".
Graham's initial attempts to recruit Nobel laureates who lived near the Repository yielded only three volunteers, Shockley among them; however, when the news media began reporting on the existence and intentions of the Repository, two of the laureates broke off their ties to Graham and did not donate. Only Shockley remained, and even he donated only once. Paul Smith was charged with recruiting new donors, and he traveled throughout California, focusing mainly on college campuses, in search of volunteers. Smith later estimated his "hit rate" of donors signed up compared to men he invited to be "six or eight, maybe ten" out of one hundred. The search was expanded to country-wide, and eventually more donors were recruited, although none of them were - then or currently - Nobel laureates. At the time of his death, Graham had expanded his requirements to allow athletes, artists, and businessmen as donors.
