Arthur A. Hartman, 89, a career diplomat who served as President Jimmy Carter's ambassador to France and President Ronald Reagan's ambassador to the Soviet Union, where he represented the United States through a tumultuous period of the Cold War, died Monday at a hospital in Washington.

The cause was complications from a fall, said a son, David Hartman.

In a career spanning four decades, Hartman held high-ranking posts under Republican and Democratic presidents and developed a reputation as "one of the brainiest and most professional members of the Foreign Service," the New York Times once reported.

During the Nixon and Ford administrations, Hartman was assistant secretary of state for European affairs, under Henry Kissinger. In 1977, he assumed his ambassadorship in France, where his tenure straddled the centrist government led by President Valéry Giscard d'Estaing and the Socialist administration of François Mitterrand.

Hartman made an impression on the French for his conspicuous presence at artistic events such as the opera, leading to a flattering profile in a liberal newspaper. "Not since Benjamin Franklin," it noted, "has an American envoy to France been given such public recognition for his culture."

He moved to Moscow in 1981 and remained there until 1987 — the longest tenure of any U.S. ambassador to the Soviet Union since before World War II and one that spanned the death of Leonid Brezhnev to the rise of Mikhail Gorbachev.

Arthur Adair Hartman was born March 12, 1926, in New York City. He served in the Army Air Forces during World War II before receiving a bachelor's degree from Harvard University in 1947.

Survivors include his wife of 66 years, the former Donna Ford, of Washington; five children, David Hartman of Rochester, Mich., John Hartman of Vero Beach, Fla., Sarah Hartman of New York, J. Lise Hartman of Paris and Benjamin Hartman of New York; 15 grandchildren; and seven great-grandchildren.

Mike Porcaro, 59, a bass player who performed along with his two brothers in the rock group Toto, died Sunday at his Los Angeles home.

He had amyotrophic lateral sclerosis, a degenerative disorder known as Lou Gehrig's disease.

His death was announced by his brother Steve, a former keyboardist for the Grammy-winning band.

A third Porcaro brother, Jeff, was Toto's drummer. He died in 1992.

Jeff, Steve and four other musicians formed Toto in 1978. Mike joined after the original bass player left in 1982. In 1983, Toto won a best-album Grammy for "Toto IV" and a best-song Grammy for "Rosanna."
