Maurice H. LeVita, 89, who had been a consulting actuary here from 1959 until earlier this year, died of cancer Jan. 30 at his home in Philadelphia.

Mr. LeVita was born in London and came to the United States in 1916. He graduated from the University of Pennsylvania and taught mathematics at Temple University.

He was the actuary for the Pennsylvania Life Insurance Department and later, from 1951 to 1959, he was the actuary for the Insurance Department of Maryland. He then moved to Washington to establish a consulting actuarial practice.

Mr. LeVita was among the first to develop the concepts of a flexible plan of insurance, which is now widely marketed as universal life insurance, and of the variable annuity, a policy that pays in accordance with changes in the cost of living.

He was a founding member of the Conference of Actuaries in Public Practice, an associate of the Society of Actuaries, and a past president of the Middle Atlantic Actuarial Club. He was author of a textbook, "An Arithmetic of Life Insurance."

Survivors include his wife, Madeline, of Philadelphia; two daughters, Aimee Weiss of Elkins Park, Pa., and Lores Gilfix of Lexington, Mass.; a sister, Betty LeVita, and two brothers, Fred and Nat LeVita, all of London; six grandchildren, and one great-grandson.
