The obituary that I will be looking at is the New York Times obituary on Nith Pran, a photojournalist.
The obituary clearly follows the guidelines of a common obituary. The first paragraph states the persons name as well as their age and what they are best known for. The second paragraph promptly follows up with the cause of death, in this case pancreatic cancer (which is properly attributed and sourced to his friend.)
The piece also features the claim to fame. It goes rather in depth into what he did in life and how he achieved it. Following this section it provides a chronology of Pran's life.
The end of the article focuses mainly on his family life, which is common in most obituaries.
