Robert J. Callahan
Callahan served 43 years with the New York State Insurance Department, retiring as chief life actuary in 1995. Johansen added that Callahan was a pioneer in developing model laws that moved away from “cookbook formulas” and toward the application of actuarial judgment. Callahan was also responsible for the initial New York regulation requiring adequacy analysis for life insurers, regulation that has served as a model for other states. He also did much to enhance the role of the actuary, by developing the actuarial memorandum on valuation matters for guaranteed interest contracts and annuities as well as for life insurance.
