Today's Daily Goodbye

The Daily Goodbye is a roundup of notable deaths here and around the world written by Post obituary writer Patricia Sullivan.

Monday's entry includes a tribute to some of the major names in the conservation movement, who recently died, including Sam D. Hamilton, the director U.S. Fish and Wildlife Service and Harvey Nelson, one of the nation's most astute wetlands and wildlife managers.

Canada also bids goodbye to its last surviving World War I veteran, Jack Babcock. Babcock's death leaves Frank Woodruff Buckles, who turned 109 on Feb. 1, as the sole surviving U.S. veteran of the Great War.

Ian Macneil, a law professor who taught President Barack Obama at Harvard and was chief of a clan in his ancestral home of Scotland, died Tuesday. He helped expand concepts of how relationships affect contracts.
