This obituary by Marc D. Charney in the New York Times is very good. (You must register to read it, but it is free.)
From the obituary:
Abba Eban, the erudite diplomat whose oratory and wit gained admiration and sympathy for Israel during the perilous first 30 years of its independence, died today in a hospital near Tel Aviv, Foreign Ministry and hospital officials said. He was 87.
Mr. Eban was an effective negotiator at talks that helped shape the destiny of his country in its early years, but it was his public voice and its impact on international opinion that set him apart. He gave elegant and passionate expression to Israel's right to exist, instilled pride and solidarity in the Jewish diaspora and was a formidable debater against his nation's enemies.
