Yes, you can.
1. Sidney Howard (Oscar in 1940)
Sidney Howard, the playwright and screenwriter, receives the first-ever Oscar awarded to a dead person. He wins it for Gone with the Wind , shortly after being crushed to death by a tractor on his hobby farm.
2. Peter Finch (1977)
The late Peter Finch is named Best Actor for his barnstorming performance as a TV news anchorman in Network (pictured above). He is the first performer ever to be Oscar-honoured after his death (by heart attack, two months before the awards ceremony).
3. Conrad L Hall (2003)
Cameraman Conrad L Hall becomes the Academy's latest posthumous honoree, and the last to date, winning the Best Cinematography Oscar for The Road to Perdition .
4. Those who came close
Actress Jeanne Eagels died of substance abuse, aged 35, before becoming the first-ever posthumous Oscar nominee in 1930, named for Best Supporting Actress in The Letter (1929). In 1955, James Dean (pictured below, in Giant) died in a car crash before being nominated as Best Actor in two successive years, 1956 and 1957, for East of Eden (1955) and Giant ( 1956). Spencer Tracy was favourite to win Best Actor in 1968, for Guess Who's Coming to Dinner? (1967) , despite - or sentimentally because of - the illness-ravaged star's death after the film's completion.
5. Heath Ledger (2009?)
Heath Ledger mania begins, ensured a long run since The Dark Knight opens some seven months ahead of Hollywood's envelope-opening hoopla. In a role darkened by the shadow of Jack Nicholson (the Joker in Tim Burton's Batman ), Ledger receives effulgent praise from the media and even Dark Knight co-actors.
