Gumbiner, who was 85 when he died in January 2009, bequeathed nearly $28.5 million in cash to the Museum of Latin American Art, in Long Beach, Calif. Of the total, he directed $25 million to endowment and stipulated that only the earnings of the endowment could be used to offset the museum's operating expenses, and that 10 percent of those earnings must be reinvested in the endowment. The remaining $3.5 million is unrestricted. Gumbiner founded the museum in the 1990s but began to conceive it in the early 1960s, when he first traveled to Latin America and started collecting post-World War II art from By 1962, he had converted his group medical practice into a nonprofit corporation that eventually became FHP International, a pioneering prepaid health plan that grew into a managed-care empire with more than 1 million members. "Dr. Gumbiner was on the cutting edge of managed healthcare before other people knew how to spell it," Charles Steller, then an executive with American Managed Care and Review Assn., said in 1990 in The Times. FHP was one of the first HMOs to embrace government-assistance programs for the poor and elderly when others thought them too risky. As of 1990, it was widely regarded as one of the best-managed HMOs in the industry, a fact that observers credited to Gumbiner's no-nonsense management style.
