Oxford alumnus Tim Hetherington, was killed in Misrata, Libya this week. The award-winning photojournalist died on Wednesday, while covering the current conflict for Vanity Fair magazine.During his time in Oxford, Hetherington worked as a staff photographer at The Big Issue. He said of his university experience in a 2010 interview, “It gave me analytic skills required of an image-maker… I learned to be self-directed, to just get on with it. That’s important for making films, where you have to turn the screw yourself.”Lady Margaret Hall, where Hetherington read Classics and English 1986-1989, paid tribute to him, saying, “Tim will be remembered by his tutors and friends at LMH for his energy, enthusiasm and curiosity about the world around him, and for his warm and gregarious personality.”Born in Liverpool, Hetherington was the winner of four World Press Photo prizes. He co-directed the war documentary Restrepo, which won the Grand Jury Prize at the Sundance Film Festival last year and was nominated for an Oscar this year.
