No. 12: Richard O. Jacobson

Amount donated in 2011: $100-million

Beneficiary: Mayo Clinic

Donor’s background: Mr. Jacobson founded the Jacobson Companies, a Des Moines corporation that operates public warehouses and trucking and packaging businesses.

Mr. Jacobson, 75, pledged $100-million to the Mayo Clinic, in Rochester, Minn., to establish a proton-beam therapy program at the clinic’s cancer center in Rochester and at a new facility in Phoenix.

The proton-therapy approach concentrates a beam directly on the tumor, sparing any surrounding organs and tissue from destruction, and can be used at a higher dosage than traditional radiotherapy, according to the Mayo Clinic.

Mr. Jacobson, who has been a patient at Mayo over the years, previously gave the institution $2-million for a professorship in molecular medicine and $55,000 to support Mayo’s clinician investigator program. A payment schedule for the $100-million pledge was unavailable.
