UNITED NATIONS, N.Y. (Jul. 1)
Col. Alfred G. Katzin, U.N. Under secretary, a rank second only to that of Secretary General, retired today for reasons of health.
Col. Katzin, who is 57 years old, was born in Capetown, South Africa, and served first in the South African and then in the British Army during World War II. Reviewing his career as a member of the U.N. staff, Col. Katzin said his most challenging job had been the clearing of the Suez Canal in 1956 when the waterway was blocked by the Egyptians with sunken ships.
