In the mid-'90s, Floyd Kimble hired Dora Vaux, one of Graham's longtime employees, to run the Foundation for the Continuity of Mankind. Vaux told the Spokane newspaper that white "racial purity" was a goal of the sperm bank and that it would not accept specimens from blacks or gays. In the same article, Doris Kimble declared that the bank would never store sperm from blacks and whites together.

Doris Kimble today denies that her late husband's foundation was white supremacist. She insists that they chose "seeds of healthy specimens, genetically strong. It does not matter what your background was." The foundation collected only from whites because "only white sperm donors volunteered," she says.

Floyd Kimble died in 1998, and Vaux died a year later. The small semen collection has not been expanded since, though the manager still mails out glossy brochures advertising the foundation: "Preserving Today for the World Tomorrow." Doris Kimble says Floyd Kimble left money for the foundation in his will—she won't say how much—and she hopes to reactivate it once her husband's estate is settled.
