In 1977, PresidentJimmy Carter nominated Aggrey to be Ambassador Extraordinary and plenipotentiary of the U.S. to Romania. In Bucharest, he met Nobel Prize winning author Saul Bellow in December 1978 who asked for assistance in dealing with Romanian red-tape his Romanian-born wife, Alexandra Bellow, was experiencing while visiting her very ill mother in a Romanian hospital. Bellow portrayed Aggrey in chapter four of his novel The Dean's December, published in 1982, describing the ambassador as "discreet, soft-spoken, almost gentle, mysteriously earnest, handsome black man" (p. 58).
