----SCOTTSDALE, Ariz. Author Elliott Roosevelt, who served his father, President Franklin Roosevelt, during World War II and later wrote a best seller about it, died Saturday at Scottsdale.
He died of congestive heart failure at his home, said Patricia Roosevelt, his wife of 30 years.
Roosevelt, 80, was a World War II Air Corps general as well as author and lecturer. He was also a former mayor of Miami Beach, Fla., and a Democratic National Committeeman from that state.
His business career included ventures in advertising, radio station management and ranching.
Roosevelt was born Sept. 23, 1910, at New York City. He attended Groton and Hun preparatory schools as well as Columbia University.
In World War II, Roosevelt commanded the multinational aerial reconnaissance wing that played a key role in the Allies' 1944 D-Day landings in Normandy, France, as well as the invasions of North Africa and Sicily.
He flew 89 missions during, was wounded twice and was decorated for valor by the United States, France, Morocco and England.
Roosevelt launched his writing career in 1946 with the publication of the best-selling book, ''As He Saw It,'' which detailed his experiences as aide to his father at five historic wartime summit conferences.
He later wrote a trilogy of books about his parents and in 1983 wrote ''The Conservators,'' a statement of his philosophy about survival of the planet.
Roosevelt lived in the Phoenix area in the late 1950s and returned to Arizona in 1989, settling at Scottsdale.
He is survived by his wife, Patricia; a brother, James; eight children; 21 grandchildren; and three great-grandchildren.
Memorial services will be held Tuesday at Scottsdale.
