"An icon of UN peacekeeping, there was no better representative of the international civil service. A mild man with the heart of alion, he is remembered by those who knew him for his dry sense of humor, his integrity and his unparalleled work ethic -- he was thefirst in and the last out every day for his entire career.

"He was proud of the UN mission in Haiti -- proud of its accomplishments in bringing stability and hope to Haiti's people, proud of his UN staff," he said.

"Luiz Carlos da Costa, from Brazil, was for many, many years a legend of UN peacekeeping operations," the secretary-general said. "His extraordinary professionalism and dedication were matched only by his charisma and warmth, and his devotion to his many friends."

"Over decades, he brought many of the finest and most talented staff to the United Nations. He was a mentor to generations of UN staff," Ban said. "He knew them; he knew their families; and his heart was always open to hear their story and to help them."

"His legacy lives in the thousands that serve under the blue flag in every corner of the globe."

"Doug Coates was a long-serving member of the international law enforcement community," Ban said. "He was a true friend of Haiti and the United Nations. He was a great police officer who believed to his core in the importance of rule of law and justice."
