Longtime internist at Kaiser Permanente, died at age 92. He attended Columbia College at 16 and graduated Phi Beta Kappa in two years, beginning medical school at age 18. He trained at Massachusetts General Hospital and completed a fellowship in endocrinology at University Hospital in Ann Arbor, Michigan. He saw an alternative to the fee-for-service health care model and in 1970 moved with his wife and young family to California to join Kaiser Permanente Los Angeles Medical Center. He rose to chief of internal medicine, a post he held for 12 years. He was known for the "Ackerman note," a handwritten note complimenting other physicians for work well done. In 2000, Los Angeles Medical Center named its library after him. He taught until the age of 84. Dr. Ackerman was a record-breaking blood donor and volunteered at free clinics and voting polls.
